Save people you follow in lists using this tool in case you want to bring them back later. Very helpful!
I follow way too many people. It's a serious problem. It's so bad that I literally can't see all of the people I follow because Twitter won't let me scroll down far enough. And even if I could it would take me forever. There are other tools that you can use to unfollow people, but Twitter doesn't seem to like it when it's TOO automated. So this is perfect for me. If I work on it a little at a time I can get things under control.
Definitely a good tool to remove inactive followers
