Just Tweet It is a directory for Twitter users that sorts people into a bunch of different categories. To get listed on Just Tweet It, head over to whichever category you fall into and submit yourself. Submitting a user is just like adding a comment to WordPress – information you need to supply includes your name, an email address (for a Gravatar), your Twitter handle, and a short description of yourself. The site works only on user submission, so it’s up to users to make it more useful.

The coolest part of Just Tweet It is that you can subscribe to notifications for those categories. When a new user is added, you can be alerted by RSS feed or email. Eventually, categories will reach a critical mass that will make the current navigation impossible so I hope to see an auxiliary navigation structure coming. Just Tweet It also has a blog that outlines some of the new things going on, such as featured users and new services. You’ll also find a few handy Twitter-related tips in the mix.
