This is a totally ugly engine to produce some stats from your Twitter feed and present them with the Google Charts API, including Tweets per hour of the day, total Tweets per day/month, top @replies and top overall @s.
The code was adapted from http://dcortesi.com/2007/12/27/twitter-stats/. None of your Tweets or other data is stored on the server once the statistics are produced.
Note: Once you submit your username and email address below, it can take up to 15 minutes to produce your statistics, especially if you have a large timeline. So that you don't have to wait around, we will email you when your stats are ready. This is the only reason we collect your email address, and it is not stored at all once your stats are generated.
If you have a protected timeline, you will have to temporarorly unprotect it for this to work.
Update: Twitter Stats now has a Google Code page.
Update: A revised version of Twitter Stats is now in use!
