A few days ago, I noted that Seesmic Web had perfected the management of Twitter contacts. I was wrong. A new service has been brought to my attention that is much, much better. Actually, it’s a must-use.

While Seesmic Web is great for a number of things (it’s arguably the best Twitter web client out there), ManageTwitter is great at one thing: managing your Twitter followers. To use it, you simply link up your Twitter account (via OAuth) and it lets you know which of the Twitter users you follow aren’t following you back, who is inactive, who is talkative, and who is quiet. Each of these are great gauges for whether you should still be following them or not.

Personally, I was able to eliminate over 200 people I was following that I determined I shouldn’t be. Most of these were users I followed a couple years ago that either were simply not using the service any more, or were no longer that interesting to me.

Unfollowing users is as simple as selecting their name and clicking the “unfollow” button. You can also do this in bulk. And hovering over any users gives you more information about them including their average tweets per day. You can also sort the various ManageTwitter fields by ‘date followed,’ ‘username,’ ‘followers,’ or ‘timezone.’

While there are no shortage of services that recommend people you should follow, I’ve long needed one to suggest who I maybe shouldn’t be following. Of those, ManageTwitter is easily the best.

Created by the Australian company Melon Media, the site notes that it has unfollowed 17092 people for 381 users in the past 3 days.
