For people who are into self-observation of personal statistics to boost productivity, this Firefox extension may just be a killer tool for you. MeeTimer is a potential procrastination eliminator that works by recording not only your time online, but more importantly, where you spend it.

MeeTime can group the sites you visit according to categories like procrastination (MySpace), search (Google), communication (e-mail) and productivity (blog). This gives you so much new and objective perspective on the actual time you spend on something. Just check the stats at the end of the day and look at how much time you spent stalking your friends in MySpace.

MeeTimer is also charityware. Check out their site for details.
