That's a good idea. I tried this after seeing your post, but I see blog lists talking about Sedo sales for the week. Is that what you are referring to? Let me know as this seems like a useful idea, and a good addon. Thanks.
it's the recent sales feed. You get a few domains everyday but domains often show up more then once so it's not a substitute for namebio. It does give you an impression of market prices and you can search your archive in Google Reader if you don't delete the feeds.
