Twit Cleaner gets your following list, then analyses the profiles & tweets of every single one of those people, looking for certain patterns of behaviour (people not talking, being over repetitive, common spam tactics, posting the same links repeatedly, etc). It's then up to you to decide who to save & who to unfollow.
Allows you to sort your Twitter contacts by last tweet date, allowing you to get rid of inactive tweeters that you may be following. You will need to enter your Twitter username & password. The only downside is that anyone following over 700 people on Twitter cannot use the service due to scalability issues.
