So, you're following a few thousand people on Twitter. You must have noticed that many of these users do not engage in conversations, never retweet anybody, or simply just ramble about nonsense stuff all day long (no links to useful content whatsoever!). You can use Tweepi’s geeky cleanup tool to filter these people out and unfollow them.

Geeky Cleanup enables you to clean-up and unfollow annoying tweeples. It lists the users you're following with information about each, and you can just pick whom to unfollow from the list!
