Ever get annoyed with people either not following you back or Unfollowing you on Twitter? Here's a good way to manage your Followers and people you Follow. This site works great if you have Firefox installed as your Browser (there are some problems if you're using Internet Explorer). The site WILL ask you for your user name and password. You can use it to follow or unfollow hundreds of users with just a few clicks. Here's the link to Twitter Karma: http://dossy.org/twitter/karma/
Also FriendOrFollow is another good Follower managing site if you're uncomfortable with entering your password. Here's the link: http://friendorfollow.com This site just shows you who's not Following you, who you're not Following, etc... You won't be able to unfollow or follow people in bulks like you could in Twitter Karma. This site is great if your variance isn't in the hundreds. If it is, I recommend Twitter Karma.
