Find new people to follow on Twitter with Twubble
If you're already logged into Twitter, all you have to do is sit back and wait while Twubble scans the list of people you follow to see who they follow. If you're not logged in, you'll have to enter your login information in a pop up box. Twubble then begins to spit out a list of Twitter users you may be interested in following. The results are ranked according to how many of your friends are already following someone. So if you have three friends who are reading CNN's tweets, and 4 that are following Download Squad, Download Squad will be higher up on the list than CNN.
You can either follow users directly from the Twubble web page, or you can click on a name to check out their Twitter profile. You can also click the "G" button to look them up on Google.
