Microsoft on Monday released a software development kit for Facebook that allows developers to create Facebook applications for Silverlight and Windows Presentation Foundation. This should expand the reach of Facebook in third-party applications as well as make Silverlight and WPF more viable platforms for developers looking to build social applications.

The SDK comes complete with samples and tools to develop Facebook applications in ASP.NET, Silverlight, WPF, and WinForms. It also features the source code for the API, components, controls, and samples.

There are currently other libraries available that allow Facebook developers to develop with other technologies, such as JavaScript, PHP, ActionScript, and the iPhone. There are a variety of others as well, which can be seen here, but these are the ones that Facebook officially provides support for.

Microsoft, as you may remember, invested $240 million in Facebook back in October 2007. Many called this move more of a strategic play to keep Google and Yahoo from getting a stake in the company. The release of this SDK is a part of Facebook and Microsoft's ongoing partnership.

If you're interested in taking a look, you can download the SDK here.

As we speak, the Foo Fighters are playing a live show on Facebook, live from their own Studio 606, for their fans on the site. The concert is utilizing the same live-stream module we have seen in used in a variety of situations in the past, including CNN's live stream of Barack Obama's inauguration. This is combined with a live video module from Livestream to complete the experience.

This is a really cool thing for the band to do for its fans and something I hope we see more of in the future. As the Foo Fighters play, they are keeping an eye on the stream of status updates coming in, sometimes responding to comments and taking song requests.

There is an undeniable trend of live events moving online. The potential audience that can be reached is fairly significant and the costs are low. As shown by the Foo Fighters, a band can just broadcast a live show for their fans, from their own studio. The social element of Facebook, combined with this event, only enhances the experience.

If you want to check out the show, we have embedded the Livestream widget below (while the show lasts).

Pandora, with new Facebook, Twitter, and Gift sharing features.

Pandora on Wednesday announced the arrival of some new sharing features for the service. In the past, you have been able to share Pandora stations, but you were forced to do it via e-mail instead of taking advantage of one of the modern social networks. Now, Pandora is enabling station and song sharing via much more efficient means: Facebook and Twitter.

These features work pretty much exactly how you would think they would. Clicking on the Facebook icon pops out a Facebook window, allowing you to share either the current song or station. The Twitter integration works in much the same way, enabling you to tweet out a link to the current song or station. When you click on the station link that someone has shared, it whisks you away to their Pandora station and lets you listen. However, the song links only go to a landing page that gives you a 30-second preview and an option to create a station based on that song. Oddly, this page does not give the user the "Buy from Amazon/iTunes" option that Pandora's main app features.

In addition, Pandora is bringing more attention to its station-gifting feature. This feature basically allows users to create an entirely new station, pair it with an eCard and send it off to someone. Pandora is essentially trying to create the modern version of the mixtape. This feature has been around for a little while, but it has gained little attention to this point. The more prominent placing in Pandora's music player may change that.

These new sharing features should boost usage of Pandora. Tapping into the previously untouched power of Facebook's social graph and Twitter can only be a good thing. Pandora is just coming off of reaching an agreement on new royalty rates for music this summer and it's working toward its goal of being profitable by the end of the year. They're also facing some stiff competition from companies like Slacker. Pandora still has a long road ahead, but opening up its service to sharing on Facebook and Twitter is definitely a step in the right direction.

This weekend, starting Friday at 10:30 a.m. PDT, Hulu will be live-streaming the Austin City Limits music festival. Hulu will be using its Watch Now application on Facebook, which has a live events box integrated so that users can discuss the concert as they watch.

You can see the schedule of acts on the Facebook application page for the live-stream. Unfortunately, the stream features only a fraction of the acts that are playing the festival. In fact, some of the biggest acts, including Kings of Leon, Yeah Yeah Yeahs, Dave Matthews Band, and Pearl Jam are missing from the live-stream lineup. Luckily, we still get to check out some great acts like Thievery Corporation, The Decemberists, Ben Harper, and The Dead Weather. There's no real indication of how the selection was made and I'm certainly grateful that we are getting a stream at all, but I can't help but wish that the full compliment of acts would be available for streaming.

We knew that Facebook had bigger plans for vanity URLs/usernames when it opened them up for registration this summer.

The popular bet was that it would create a mention/reply system similar to Twitter's @replies. That was shot down this week when Facebook launched its mentions system, which uses real names. But on Thursday, Facebook started letting users log in with their usernames.

This might not seem like a big deal at first glance since most Web sites use username log-in. But this is a time saver, compared with typing in your full e-mail address every time. I still suspect that we will see our Facebook usernames being used for more things in the future, though it's unclear what those things may be.

Friend Lists has long been an underused feature in Facebook. The feature allows users to split their friends up into different groups, choosing different privacy settings for each one. It is clear now that Facebook has bigger plans for the feature and it's getting serious about trying to persuade people to use it. Recently, Facebook automatically created Friend Lists for its users in an effort to help them filter and better consume their Live Stream. Now, Facebook has redesigned their Chat feature in order to take advantage of Friend Lists. Users can now organize their previously unwieldy Chat lists into groups, defined by their Friend Lists.

Upon loading up Chat for the first time since this change, Facebook users are prompted to say which Friend Lists they want to add to Chat. Users can segment these friends into sublists for Chat, and everyone else gets dumped into a generic "Other Friends" list. This alone is going to be enough for a lot of users to put these previously uncategorized friends into a List. While there apparently wasn't enough motivation for users to group their friends before, now that they are grouping them for the purposes of a clean Chat list, the rest of the functionality of Friend Lists throughout the site is unlocked. Suddenly users can now filter by these Lists that they have taken the time to create, send Inbox messages to whole lists, and create customized privacy settings. I have no doubt that Facebook has more plans for Friend Lists as well.

Not only does this new grouping by Friend Lists give users a cleaner view of their online friends, but users can also toggle whether they appear offline or online for a certain group. This is yet another feature that is going to provoke people to start organizing their friends.

Facebook has been doing a lot of work lately, building new functionality into the site. On Friday, the site brought "refresh alerts" to its home page and now it just rolled out this newly enhanced Chat. It looks like the Facebookers are working overtime to try to win back the hearts of some of the users that they angered in their last major redesign.

For the uninitiated or nongamers out there, the Konami Code (UP UP DOWN DOWN LEFT RIGHT LEFT RIGHT B A) is arguably the most famous cheat code in video games.

It has been used in countless games and has references in multiple forms of pop culture. Lately, some sites have taken to using the code to trigger amusing events on the page. Recently, ESPN used the code to spawn unicorns and rainbows all over its pages.

Now, Facebook has dropped the code into its site. When entering the Konami code, followed by Enter, a lens flare is generated every time the user scrolls or clicks something on the page.

This Easter egg is becoming more and more common, and a site has even popped up to track the sites using it. (You will have to enter the Konami Code to see it, of course.) ESPN has since taken its Easter egg down, but those that remain include Facebook, Digg, Google Reader, and our very own GameSpot.

It's nice to see Easter eggs making a resurgence since they have been largely frowned upon by the tech industry in recent years, with Microsoft formally banning them from its software in 2002.

To try out the code for yourself on Facebook, load up a page on the site, hit UP UP DOWN DOWN LEFT RIGHT LEFT RIGHT B A ENTER on the keyboard, scroll around and enjoy. Instructions on how to activate other Konami Code Easter eggs around the Web can be found at Konami Code Sites.

Updated at 11:30 p.m. PDT: This blog misreported the percentage of swine flu interest on Facebook member pages in the states of Texas and Mississippi. The correct percentages are 0.82 percent and 0.29 percent, respectively.

There have been a lot of resources that have surfaced to help track the newly spreading swine flu. On Monday, we covered some of these online resources to help you stay on top of it. Tuesday night, Facebook released some interesting data on the conversations taking place around the swine flu outbreak. The company has posted a photo album on Facebook's official fan page, containing images that detail the growth of the discussion as well as the geographical distribution of people talking about swine flu.

As this image shows us, there is a wide range in the percentage of people talking about swine flu in wall posts from state to state. Texas has 0.82 percent of its Facebook users mentioning swine flu, while Mississippi only has 0.29 percent. Hotbeds for the outbreak, such as California, Texas, and New York obviously show the greatest concentration of users discussing swine flu. The numbers in Canada are significantly lower than those in the U.S., obviously showing that the Canucks aren't getting as concerned yet.

All of this data was generated using Facebook's Lexicon service, which tracks how frequently certain terms are mentioned in wall posts. The Facebook data definitely gives us a better understanding of who is talking about the outbreak and can help us to visualize the spread of information on the subject.

The role that social media has played in the spread of information throughout the swine flu outbreak has been significant. Some would argue that social media has helped to fuel the fire, along with the constant coverage on the news. For better or for worse, social media is likely to be one of the primary mediums through which information spreads in a crisis moving forward.

Check out the Facebook data here.

Last fall, Facebook's fbFund had a successful grant competition where it shelled out $25,000 in seed funding each to 25 promising Facebook Platform developers. fbFund is following up that effort by starting a Facebook Platform incubator in Palo Alto, Calif., this summer. fbFund will pick 50 finalists out of the applicants and choose "a few lucky start-ups" to get up to $100,000 in funding and spend the summer in Palo Alto (Facebook's hometown), participating in tech talks and developing applications.

Those who get to spend the summer in Palo Alto will also have access to an impressive list of mentors, including Facebook itself, Accel Partners, Flixster, Founders Fund, RockYou, SGN, Slide, Tapulous, and Zynga. The program lasts from early June through late August and there's no word if there are plans to extend the incubator past the summer.

It sounds like a pretty sweet deal for aspiring Facebook Platform developers who need the funding and mentoring to take their business to the next level. The hope is that it will also spark more interest in developing for Facebook Platform since the iPhone and other platforms have been stealing all the buzz lately.

For the developers out there who are interested in applying for fbFund's incubator, the application is here.
