I was just Googling and got through a site which gives all the information related to twitter accounts. The site is called tweetrush. I was really surprised to see the top tweeter who does an average tweet of 1349 tweet a day and has done 129,474 tweets since July 19th 2008.
I guess this user does nothing other than tweeting or has some automated system to do it. How many tweets do you do a day? You can also check your stats by visiting http://tweetrush.com/Yourusername
The stats includes information like the last 7 days usage, total number of tweets, and your average use per day.
