WeFollow: user-tagged Twitter directory
On the other hand, here's why I don't care about WeFollow. It's top-loaded, in a kind of leaderboard format. The front page displays the most popular people in the most popular categories. So, although the category list is deep, all the good stuff is hidden. Sure, you know Shaq's on Twitter, and you know who @ev is, but a front page that shows all the folks you're already most likely to follow doesn't seem the best way to make people's Twitter streams richer. It does seem to be a good way to get Kevin Rose more followers, though. In WeFollow's defense, though, I'll admit that the user-tagged system of adding yourself is cool and convenient.
