Google Zeitgeist
I found this the other day. Never actually used or heard about it before. It really is an awesome little site / tool / sub-Google client.
Google Zeitgeist gives you a peek into Google’s peak searches.
Check it out, you can go back as far as 2001 and see the high points of each year, month or week. The above image is the zeitgeist for the end of 2007.
