Want to go through your Twitter account with a fine tooth comb? Try Tweepi. You can choose to look at everyone on your list and see who does and does not follow you in return. You can look at a list of just who does not follow you. Or, you can look at a list of who follows you that you may have missed. It's lovely. Works well, even though they say it is very beta. Took me some time to get through all my followers and non-followers and prospective followers but I did. I feel better about the whole Twitter experience now.

I had been using Friend or Follow (I won’t put a link :-), but it takes a long time & a lot of back and forth. Sounds like Tweepi might be better. Thanks for the heads up on it.
