This might simply be deserving of the links topic, but WHO CARES I RUN THIS PLACEEEEEEE.
I found a site called
Wakoopa, which is a neat little place/application that tracks the programs you run, not only letting you see your own usage statistics, but adds them to a global database to see which are most popular.
Here's my usage statistics thus far. If you sign up, post yours too. They even have a Mac version.
