Twitter Grader logo
http://ping.fm/URbiG is a nice tool that grades your Twitter account based on users, activity, etc. Think Technorati for tweets!
Check out your own or well known tweeters and see how they score: http://ping.fm/t1P52 – not to make too big a thing of the fact Neoco tweets score 90 out of 100 (up from 89 just 2 days ago)!
You can also check out the Twitter elite (http://ping.fm/TAlgctop/countries) for some interesting stats – like Japan being almost 10 points clear of the USA for quality!
