I came across this cool site that allows you to see all the people who aren’t following you own Twitter, and unfollow them real easily.
- You just visit http://manageflitter.com
- Connect with your twitter account
- Click the “NOT FOLLOWING BACK” button
- Where you see the Page overview, hit the expand button
- Highlight the people you want to unfollow, and click the “Unfollow Selected” button on the right.
