As Twitter surges toward an estimated 12 million registered users by year's end (though some new stats may disagree), some of us are starting to deal with what we recently dubbed "followholism." You've followed so many people, it's hard to keep up, and it's probably time to do a little housekeeping.
But where do you begin? Twitter's own tools for managing followers are subpar. It's nearly impossible to figure out who among your followers are following you back, and the interface for paging through followers is clumsy and difficult to use. Fortunately, Twitter's API has given rise to a vast universe of amazing third party apps. So we've assembled a toolkit below of 10 services that can help you take control of Twitter and organize your followers. If you know any other tools that would be helpful for organizing tweeps, add them in the comments.
