With so many URL shortening services out there, this was bound to happen to at least one of them: Trim is shutting down. According to a blog post by parent company Nambu Networks, it was an expensive and fruitless effort.

"We simply cannot find a way to justify continuing to work on it, or pay its network costs, which are not inconsequential," the post read.

Those expenses may have been particularly encumbering recently, when the service, found at Tr.im, was hit by a denial-of-service attack last week that knocked it offline.

The blog post was tinged with more than a hint of bitterness. Twitter, the service that led to the explosion of URL shorteners as Web users needed to truncate lengthy addresses to fit into a 140-character space, has shown a clear preference for Trim rival Bitly. Twitter uses Bitly as its default URL shortener, and it's even been rumored that Twitter may acquire it altogether.

"Twitter has all but sapped us of any last energy to double down and develop Tr.im further," the post read. "What is the point? With Bit.ly the Twitter default, and with us having no inside connection to Twitter, Tr.im will lose over (in) the long run no matter how good it may or may not be at this moment, or in the future."

What the company hasn't said: what will happen to existing Trim URLs? It's likely that Nambu Networks hasn't yet decided. If Trim is completely closed, that would mean that those shortened URLs would turn into broken links. It'd be possible to close it to new entries but keep existing ones, except that wouldn't solve the financial problem.

One commenter on the Trim blog post suggested that perhaps the service could live on in the form of an open-source project. But for now, its fate remains up in the air.

One of the myriad URL-shortening services out there, found at Tr.im, suffered an outage for some time Wednesday, rendering many links unable to redirect.

The service--which is owned by a start-up called the Nambu Network--believes hackers are to blame. "From this end it appeared we suffered a denial of service attack, and we took appropriate action to get the website back to full service," a Trim representative said to CNET News in an e-mail.

There's another, less likely possible culprit: Airline JetBlue hit one million Twitter followers on Wednesday, and announced a one day-only commemorative deal that would shave 20 percent off the cost of any flights booked through a promotional link. It used Trim as the URL shortener for the link in question, and acknowledged in its "JetBlue Cheeps" Twitter-deals account that heavy volume from the sale may have unexpectedly caused the outage.

Whether or not it was the JetBlue promotion that crippled Trim, there's a bigger-picture problem here: URL shorteners like TinyURL, Bitly, Owly, Isgd, and related offerings from Digg and StumbleUpon, are a huge deal when we've all grown accustomed to fitting stuff into 140-character fields. Some, like Bitly (which Twitter uses as its automatic link shortener and which has been talked up as a possible acquisition for the microblogging company) and Trim, offer some tracking data and analytics surrounding the links plugged into their systems.

But when one crashes, so do all the links associated with it. Or what happens if a URL shortener goes out of business altogether? There would be a whole lot of lost, broken links out there. Some very small URLs could have a very big impact on the organization of the Web.

After two days of silence, Digg has gone on the record to officially acknowledge the change in how its shortened links are redirected, as well as clear up how links will be handled in the future.

The change, which took place on Sunday, had links which once lead directly to a story's source, redirecting to Digg's story pages instead. The new behavior appeared only on stories that had been submitted to the site, leading to confusion on where users would go when they clicked on a shortened Digg URL.

In a post on Digg's company blog, CEO Jay Adelson explained that the new way of handling shortened URLs would remain in place. As a concession to early adopters, Digg URLs created before Tuesday would continue to link directly to the source. But going forward, all new links will retain the newer behavior of redirecting to Digg story pages, unless the page had never been submitted as a story, or the viewer is registered and logged in to Digg.com.

Despite how the the DiggBar and integrated shortening service were introduced to users earlier this year, Adelson said Digg never wanted to end up as a URL service provider.

"Our strategy with Digg short URLs is to facilitate sharing of Digg content, not to be a conventional redirection service," Adelson said. Digg founder Kevin Rose had said something along the same lines in a Sunday night appearance on Leo Laporte's This Week in Tech.

So far, the change has resulted in a lot of user distrust. Many people who used the service to shorten URLs have vowed never to use it again, while others simply chided the company for changing the behavior of links without first alerting users. Digg has caved to unhappy users in the past, but this change has more to do with Digg's business model than previous feature changes.

The DiggBar remains one of the company's most controversial features. While fervent users continue to use the service, it was initially a big turnoff for many publishers and casual users. Along with the structure of user comments, the DiggBar has endured a lot of changes since its inception, having had much of its functionality made optional after users and critics alike bashed its operating methods.

Still, the change in URL behavior serves several important purposes in moving Digg forward as a business. One is to get more page views and boost unique user counts from people who must first visit Digg's story pages before visiting the source story. Another is to grow user adoption of the DiggBar, since using it preserves the old way of clicking on links and going directly to the source.

Whether Digg will continue to change its functionality in order to push users toward enabling the DiggBar remains to be seen.

Over the weekend, social news site Digg changed how its links work in a way that gives the site an increase in the number of users who visit.

Users of the site's URL-shortening service noticed that if the Web address they had shortened had been submitted to Digg, the shortened URL would then take its visitors to the story's page on Digg instead of the page it linked to. At least it was this way for users who were not logged into Digg; registered users who had turned off the DiggBar (and who had a recent log-in cookie from Digg) would not see the change in behavior.

The problem

This may seem like a small change, but it's a big knock on Digg's shortening service, and for Digg's credibility at maintaining features.

Introduced in early April, the DiggBar was originally intended as a service that did three things: one was to shorten links and act as a redirection tool. The second was to bring Digg features along for the ride with a framed bar that would appear on the top of the page and provide a simple way to view user comments, related stories, as well as other Dugg items from that same site. The third was to provide a simpler way for users to publish content, either to Digg itself, or places like Facebook, Twitter, and e-mail. This included giving users the capability to shorten a URL by dropping a Digg.com/ in front of the site's address.

Despite the bevvy of features compared to some competing URL-shortening services, both users and publishers alike found fault in the DiggBar. Users had problems with the service since it drastically hid information about the site they were on, including the URL in their browser's address bar, and any bookmarks they saved, which would retain the DiggBar. For publishers, there was the worry that users would choose to comment back on Digg instead of on their own pages, as well as SEO damage from search engines not properly indexing and attributing traffic since Digg.com was the redirector.

Digg's solution, which came just two weeks after the DiggBar launch, was to make the whole DiggBar experience something users had to opt-in to see. This meant that registered users of the site would only see shortened Digg URLs, and the DiggBar by choice. Stray visitors of Digg wouldn't see either.

A feature that was once quite controversial, the DiggBar is now a rarity, unless users are registered with Digg and have opted-in to see it on Digg story links.

In effect this left the DiggBar as something power users could take advantage of, but that casual users would never see--reducing the entire DiggBar feature down to URL shortening.

This clearly wasn't good enough for Digg, since this move nets the site more ad impressions and unique user tracks than it would by acting as a redirection service alone. Back when it was originally introduced, the company was able to get by since the DiggBar displayed ads when people were using certain features such as viewing related content, Digg user comments, and other stories from that site's particular source. But, without the DiggBar on top, and without any kind of recognition--other than in name, Digg was getting none of these benefits.

So is Digg's shortening service now just a way to shorten links to Digg.com pages? Digg founder Kevin Rose went on to say as much in a Sunday night appearance on Leo Laporte's This Week in Tech, citing that the company was having to internally juggle certain shortened-URLs that had become popular from outside sources. Particularly, ones from Twitter where the source site would be on the receiving end of an increasing amount of traffic, but because of the lack of a Digg frame bar on the top of the page, it wasn't easy for users to...

TinyURL Generator is a new experimental Firefox extension that makes it easier to grab a TinyURL of whatever page you're on. Once installed it will automatically create and save a smaller, shorter URL from TinyURL.com when new pages are visited. The TinyURL is then copied to your clipboard for easy copying and pasting in an e-mail or IM conversation.

For frequent TinyURL users this might be a better route than using one of the many available bookmarklets since it saves you a click and a copy/paste. On the flip side, it doesn't work so well when used in tandem with Web mail services because it will copy over the URL of your e-mail provider over the site you just visited. If you want to avoid that, be sure to have your Gmail, or whatever service you're using, open beforehand.

Update: As reader raggermany points out this is very similar to TinyURL Creator which also gives you a TinyURL for any page you're on. The big difference however is that TinyURL Generator converts links passively in the background.

If you're looking to share an MP3 with a friend, or with a bunch of other folks on Twitter, worth checking out is Songly. The service takes the URL of any MP3 that's hosted on the Web and will both shorten it for micropublishing tools like Twitter, as well as package it in a slick little Flash player. This is especially useful since your recipient can play it back without having to download it first.

Compared to TinySong, which we looked at back in June, the big benefit here is that you're not limited to a catalog of licensed music. The flip side of that is that the music track must continue to be hosted somewhere for it to keep playing.

In addition to its Web interface Songly has a freshly-released Firefox extension that lets you right click to shorten and share any audio file you come across. If you're feeling extra geeky, you could theoretically feed the Songly URL into another shortening service like Bitly to keep track of how many people click on it.

Songly takes an MP3 track hosted somewhere and gives you both a Flash player and a direct download link. Its big feature, however is the option to send its shortened URL out to Twitter.

UPDATE: Gossip blog Valleywag decided to out this for what it is--an April Fool's joke. Oh, well, it would've been funny to see people pick up on it.

With the rise of "microblogging" services like Twitter that limit the number of characters in a post, URL-shortening sites like TinyURL and URLtea have taken off. A new service that just launched, Urlrurl, promises to step it up a notch by tracking the popularity of online memes that are tossed around the Web through viral link-sharing.

"Urlrurl.com stands out from other link shortening services because of its patented Relay-Stick algorithm," a release from the new start-up read, "which dives into the links put through its shortener and exposes common memes across the pages people are clicking on." That sounds pretty cool. It's also connected to the Twitter API, plugging it into one of the biggest pools of URL-shortening activity on the Web.

And there's more: "In early June, a free stats program will launch, as well as a premium service for bloggers and publishers," the release continued. "The premium service will allow publishers to register their site with Urlrurl.com and receive deep insight into how content and memes have traversed the web." Considering that no one can really tell where Internet memes emerge these days--4Chan, Fark, Digg, iVillage--this kind of service, provided it actually works, could give some interesting and oft-hilarious insights.

Urlrurl is headquartered in New York with development offices in China, and counts TechCrunch czar Michael Arrington among its angel investors.

Moourl.com has the cutest URL shortening site we've seen

Link or URL shortening services are nothing new--TinyURL, for example, has been around since January 2002, when site creator Kevin Gilbertson wanted to link directly to newsgroup postings with really long addresses. Indeed, that's the true impetus behind these services; taking really long and unwieldy Web links (to an Amazon or eBay item, for example), and shrinking them down to a more reasonable size. Simply copy and paste the offending URL into the field, hit enter, and voila, you'll get a much shorter link. These shorter links can then be shared via IM or e-mail without the URL breaking, and they are also very useful with micropublishing tools such as Twitter, where character count is at a premium. Most of these services also redirect the links straight to the original address. There are literally hundreds of these link shortening services out there, but we've decided to break it down to 10 that we like the most. Here they are in no particular order:

• TinyURL: Arguably the most well-known of the services listed here, TinyURL was probably also one of the first. One of TinyURL's most appealing features is that the short URLs it creates will never ever expire. It offers a browser bookmark button that'll provide a TinyURL of your current page, and there's a preview feature as well.

SnipURL is a link shortening service with a social twist.

• SnipURL: Also known as Snurl and Snipr, SnipURL is a URL shortening service with a social twist. You can sign up for an account which lets you edit URLs, subscribe to the RSS feeds of your latest Snips, password protect them, and snip multiple URLs at once. It also has an open API for developers. Twihrl, a multiaccount desktop client for Twitter, uses SnipURL for its long URLs, for example. Another bonus is that you can choose your own "nickname" for a link. For example, http://snipurl.com/cnetcrave will redirect to our Crave blog. Like TinyURL, the SnipURLs will never expire, plus there's also a help forum for support.

• Shorl: For a simpler approach, Shorl is a decent alternative. It has a very clean interface without a lot of ads, plus you can sign up for an account to retrieve the statistics of the shortened links.

• Rurl: Rurl is a URL shortening service ideal for mobile use, since the page is very phone-friendly, and the URL itself is really short (about 19 characters long). The short URL is also good for Twitter, because of its character count limit. Like SnipURL, Rurl also has a developer API.

• Metamark: Metamark also prides itself on providing really short URLs (about 20 characters long), but like SnipURL, Metamark lets you add an optional nickname to a link. There's also a "secret" option to add a secret word after the URL if you don't want people to guess the link. You can sign up for an account if you wish to retrieve the statistics associated with your link. Unlike the above services though, the links from Metamark do expire after five years, so take note of that.

• Notlong: Notlong kicks it up a notch by not only shortening the links, but it also lets you pick a subdomain name. For example, I just created http://webware.notlong.com a second ago. Another great thing about Notlong is that the moment you create a Notlong URL, it presents you with a password with which to check the statistics of the URL, no registration required. However, you'll have to be creative to pick a subdomain that hasn't been chosen already.

Tweetl is a link shortening service built for Twitter.

• Tweetl: With the popularity of Twitter, a service like Tweetl was bound to come along. Its slogan is "Little Links Built for Twitter" and the links are indeed sublimely short (about 17 characters long), which is good for fitting within Twitter's 140 character count limit. You can get stats of any Tweetl link without signing up just by entering the site ID after s.tweetl.com (Like s.tweetl.com/[id]). You can also add a tag to each Tweetl link by adding a question mark and whatever you want at the end of a Tweetl link, such as this: http://t-l.cc/[id]?insert-tag-here.

• URLTea: URLTea has a dead simple user interface--simply paste in your link into the field, hit enter, and the shortened link will immediately be copied to your clipboard. Similar to Tweetl, you can add tags after the URLTea link with a question mark, such as this: http://www.urltea.com/l?insert-tag. We also like the gingham background; it's a nice touch.

• MooURL: MooURL is quite possibly the cutest link shortening site ever, with an adorable cow as its mascot. Like URLTea, a shortened link will be immediately copied to your clipboard. Sure it doesn't have a lot of statistics-tracking like the others, but it's just so cute.

• ICanHaz: Capitalizing on the Lolcat trend is the folks over at ICanHaz.com. Its slogan is "I can haz short urlz now? kthx", which is typical of Lolcat speak. Like SnipURL and MetaMark, you can select a nickname to be added after the URL. For example, http://icanhaz.com/webware directs to Webware. The downside is that you have to enter in your e-mail address if you want to edit the URL in the future. Also, unlike SnipURL and MetaMark, the nickname isn't optional--you have to enter a nickname regardless of whether you want to, and your chosen name might already be taken. However, the best thing about this service is arguably the Lolcat speak aspect of it, for those who are into the Lolcat meme.
