If you hadn't seen this already, Amazon has begun syndicating popular content from their site. It's pretty powerful stuff and Paul Bausch has an Amazon Feed Builder up for your enjoyment. I promptly built an Amazon Alternative CD's Top Sellers watchlist for my news reader, Newzcrawler. I immediately bought two of the top ten CD's and now Liz Phair and Radiohead are on their way! It's a good thing there isn't an Amazon Sports Cars Top Sellers list yet.
