I've always loved myYahoo for it's configurability. I've loved the idea ever since I saw the BBCi TV site - sadly no longer running afaik. Then today I was looking at myWeb and found this site Google U.S. Government Search.
I love Yahoo!, but I think this configurability is really cool!!!

sole test of the validity of any idea is experiment."
