TweetStats, a way to get all types of statistics for your Twitter account (or anyone else's actually), has some interesting graphs by default.
The one about interfaces (pictured), or "how you twittered" it could be called, seems to be a little inaccurate unless I'm completely mistaken. According the graph it says I've somehow interfaced with Twitter via IM nearly 400 times. I don't believe this to be true since I do not remember ever sending a message through IM to Twitter.
My memory is more muddy water than anything - so I'm probably wrong here. And I want to be clear that I'm not totally placing the blame on this tool, but perhaps Twitter somehow logged almost 400 of my statuses as being from an IM client when they really weren't. Who knows, who cares, still cool.
