Google Analytics

It would be really useful is if there was a tool like Google Analytics, but for people rather than websites.

I'm envisioning either a desktop application or a Firefox plugin that tracked what websites I went to, how much time I spent on each website, entry time, exit time and stopped timing after a certain time of inactivity. A desktop app would be more effective because then it could also track time spent in, for example, your text editor

This should put paid to the woes of time logging, and many of the inaccuracies too.
