Despite disabling it years ago, Google Web History was kind enough to log all my searches since October 2005. I’d advise seeing what they opted you in to without permission or due to “bugs”.
Anyways, it seems these are the sites I use most after doing searches:
I use Facebook 10 times more than I use Bebo so I dunno where that came from.
This site: http://www.irf.com/ is the one I apparently clicked 5th most in 2.5 years. Uhm, I’ve never been to this site until I saw it in my history.
