Are you guilty of following people on Twitter simply because they follow you? How will you know if they stop following you? Or maybe the reverse is true, and you want to see who is following you, but that you’re not following? In either of these situations, FriendorFollow.com can help.
With FriendorFollow, you input your Twitter username, and then can choose to see a few lists: people that you follow who aren’t following you back, people who follow you who you aren’t following in return, and mutual friends. If you authorize Twitter from within FriendorFollow (which uses the Twitter authorization API), you can follow and unfollow people from within the site. FriendorFollow is a great tool if your Twitter follower list has gotten out of control.
