Several of the award winners were familiar, and many of them I had not heard of before. I thought that some of the business productivity sites from 37 Signals - Writeboard, Basecamp, Campfire, Backpack, and Ta Da List were really cool.
I clicked around several of the different award winners, but I was really impressed with Pandora. I've created a couple of different radio stations and it is really amazing how they parse down the music and then find similar artist. This is definitely a site that I will continue to use. This is a great way to find new music.
