The Twitter User Classify script is a Twitter Greasemonkey script that allows you to see a ranking of the profile of Twitter users. The rankings range from:
1:5 = twittercaster
1:2 = notable
1:1 socially healthy
2:1 newbie or social climber
5:1 twitter spammer
The script places a small bar at the top of any Twitter profile (including your own), with a listed scale ranking. The bars are also color-coded based on rank to help you remember what profiles you can safely avoid and which ones might be of interest with just a quick glance.
