Tweetstats

Tweetstats is a simple tool that allows you to get detailed stats of your tweets, who you sent them to the most and when you usually sent them. Simply enter your Twitter username, let the site do your calculations and then explore!

There are graphs to cover:

• Your tweet tineline - how often/how many tweets you do in a week/month


• Your tweet density - when you most often tweet


• Who your @ reply to's are


• Who you are re-tweeting


• others

But this is not limited to YOU. As long as you know someone's twitter id you can "study" what others are doing.
