Wakoopa’s tracker logs what applications you use and for how long, updating your personal profile every 15 minutes. On the website, the aggregate data lists the most recently used applications and most used applications of all time. Each application has a profile that lists the people and groups who use it, reviews, and tags.
on the other hand, microsoft already has all this usage tracking infrastructure, but what are the chances of that being widely available? maybe all this data could lead to non-annoying clippy suggestions. that would actually be kind of awesome.
