Twitterholic is the definitive site to search for popular Twitter users. Twitterholic has a list of Top 1000 popular users. To be on the list, one has to twitter constantly. Only the most popular Twitter users are crawled everyday, the other users are crawled randomly.

The user can also find out his Twitterholic ranking by providing his username to Twitterholic. If Twitterholic has previously crawled the user's account, the rank would be displayed. If you are new to Twitter, you wont be able to check out your ranking on Twitterholic for a while. The user is provided with his overall Twitter ranking along with his ranking in their metro location. The ranking is calculated based on the number of followers. The date your account was last crawled is also shown. The user can also request Twitterholic to crawl their statistics.

Twitterholic is a really good tool to find the influential people in Twitter either in your area or throughout the world. I really love their tagline : Don't your thumbs hurt yet? ;o)
