I have made a hack that makes it possible for me to track the amount of hits for different search phrases over time. The system is open so that people from all over the world can add new phrases. It seems like it is becoming more popular than I imagined when I made it so this is starting to get interesting.
Check out trendmapper here.

Lately I have experienced a bit of trouble in the system that updates the charts on Trendmapper.com
It seems like the scripts that collect data to the database works fine, so the search phrases should be up to date. However, some of the charts on the websites seems out of date. I’ll try to fix this as soon as possible.
That is good news. Thx!
Hi Erik
Just found this explanation. Please ignore my previous comment. Hope it gets going soon, Trendmapper has been fun.

Ant reason why the Trendmapper website is not working today?
