I have been asked several times of a tool with which you can unfollow certain people at a click.
Twitter Karma is what you need.
There are sites like Friend Or Follow which are similar but you have to follow/unfollow manually.
Have you used it?
Any other substitute?
I've tried unfollow websites but they don't seem to work for me. So I've actually had to go through and manually clear out my twitter account (which took FOREVER!). I know that there are probably tons of services that will unfollow people automatically if you just go to google and search.
Yeah. I have the same problem Corey has. Karma just takes forever to load! There are tools that let you unfollow/follow people manually easily, like my tweeple.
Karma is an awesome tool, but apart from that there is Untweeps too and mycleenr too.
As you quicly mentionned, I prefer to use FriendOrFollow because I can see who I am about to unfollow (and who I don't want to), then I may use a tool such as Karma.
