Good Twitter tools for segmenting

Hi guys,
I’m looking for a good Twitter tool to segment my followers into groups.
Does anyone know of anything that will do this easily?

I would suggest TweetDeck you can use for to update Twitter, Facebook, MySpace and LinkedIn!
…and a short tutorial for managing followers:

I’m currently using TweetDeck but I’ll check out the tutorial as I’m probably not using it to it’s full potential. Thanks DT.

So did you find it helpful?
