It’s been a while since I released a full web app (no, shouldiusetablesforlayout doesn’t count), so I thought I spend a few hours and created keywordfinder.org:

It is a service that returns the 20 most successful keywords for a search term you enter and the first 20 sites that come up when you do a search online.

Hopefully this is useful to some, I just had fun playing with BOSS and some YUI CSS to create the whole thing from scratch in one morning :)
