Once a while I tend to remove some twitter users whom I follow and at the same time do not follow me back. Of course I do have some of my own criteria and I don’t mind following someone who are providing me with great information on Twitter.
One of the easiest ways to unfollow people who are not following you on twitter is by using Twitter Karma.This is because Twitter Karma will simply search through your contact list, then list those who follow you, those who don’t and mutual followers. Then you could filter manually and when you are done, simply check “Bulk Unfollow”.

It is good to do some clean up when you are following too many people and you do not have much followers. It is important to maintain certain ratio so that people do not perceive you as a spammer who uses a computer to do mass following.
For new follower, I do use TweetLater to do vetting on users and my condition is also base on the ration someone is following compare to their followers. So remember to unfriend people who are not following you back on twitter, provided they are not active or their tweet they do is useless to you. I will explain about TweetLater service next time.
