WeFollow is a new site, that is supposed to be a user-generated Twitter directory. The idea is you send it three hash tags that describe you, and you get placed in their directory with others with the same.
Looking at the front page, though, WeFollow simply serves to highlight the most popular people using twitter — it’s a list of the same people we always hear about, like Ashton Kutcher and Shaq and Kevin Rose (hmmm….he started the site.)
Not sure what the purpose is, though. Seems redundant.
