Twitter is community-driven, and many of its features and vocabulary have been born from that community. It only makes sense this community has resulted in an entirely new community: the Twitter Fan Wiki. Perhaps the best feature of the wiki is its gigantic page dedicated to Twitter apps. The list is composed of hundreds of applications, games, utilities and other Twitter resources, resulting in what is probably the most comprehensive guide to Twitter you’ll ever find. Similarly, the section called “The Cast of the Twitterverse” has lists of Twitter users that may be of interest to you, from universities and organizations to minor celebrities and news services. That said, some of the other pages in the wiki could use attention. Maybe you’ll want to contribute? Make your way over to the wiki and add your two cents to the mix. The more people contribute, the better the wiki gets.
