Refollow is yet another online Twitter app which allows you to manage your followers/friends. Like Tweepular, it allows you to bulk follow, unfollow and block user with two clicks and its very easy to use. It helps you filter your Twitter friends to find the ones that are following you, the ones you are following as well as the ones that are not following you and the ones you are not following.

All in all, its a convenient way to manage your Twitter friend network. It’s quick and easy to use although they still require your username and password. Let’s hope they implment OAuth protocol soon (like other Twitter apps) so you don’t have to give out your password in order to use it.
