I played around a bit with doing sentiment analysis on my own tweets, and realized a lot of what I tweet is more negative than I intend it to be. I figured others might find it interesting to see their own tone, as people tend to respond in the same way. This gives you a report on the sentiment of your tweets, of what sort of responses you get and what sort of tweets you like.
And it also gives a high score list of the tweeps with the highest scores. I mean, why not :)
