If you've been on Twitter for too long, or gone on binges where you follow too many people at once, you can end up with a crowded, even toxic Twitter feed. In the twelve years I've spent on Twitter, I've ended up following an unwieldy crowd of over 3,700 accounts. I can't make a big dent just by manually unfollowing people in my feed, so I use ManageFlitter, a powerful tool to sort and act on my followers.
