Digg.com founder Kevin Rose is at it again with a Twitter directory called WeFollow. And although it's capturing much of the limelight right now, it's not the only service of its kind. In fact, there are quite a few sites that let you search for other users or see who the top users are on Twitter. While some are quite useful, you probably won't be surprised to find out that not all are created equal.The standouts
TwitterCounter. TwitterCounter shows you your worldwide rank in terms of how many followers you have. The site includes a full list of the top 1,000 Twitterers, and regardless of whether you have 5 followers or 5,000, you can look up your own Twitter account to see how many people have added you in the past few days, how many you'll likely have in 30 days, and more. It's also a great spot to find folks you might not have known were on Twitter.
TwitterHolic. If you want all the functionality TwitterCounter provides, TwitterHolic probably isn't for you. Sure, you can search for yourself and others to see how many followers they have, and how many they've added over the past few months, but there isn't nearly as much in-depth data on the Twitter community at large. That said, it features the same list of 1,000 Twitter followers, and based on my testing it's just as accurate as TwitterCounter, which means follower counts are usually within 10 to 15 followers of the real figure. It's also a great place to find who the top Twitterers are.
WeFollow. It might be new, but WeFollow has already made an impression on the Twitter Community. The site groups together Twitter users and messages using hash tags--words that can be added to your Twitter messages and begin with an "#". Twitter users can update their stream with a tweet containing up to three hashtags they want to be included in and WeFollow adds their messages into the proper categories. The user list in each category is organized by the number of followers they have. I was generally impressed by the service and found that it's the best of the bunch, even though it's not as full-featured as I would have liked. But for directories, it's top-notch.The rest
