If LastFM is for music, Wakoopa is for softwares. A small tracker can be downloaded at the website which monitors the softwares you use on your computer. Very detailed statistics are recorded about your daily software usage and you can visually see it in the form of a pie chart. Like LastFM suggests similar music this website can suggest you similar softwares.

I find this website fun. The most fun part is working to increase your reputation in the website. To estimate your reputation, you are given ‘levels’. Levels page is really worth checking out.
