StumbleUpon Gets into Search « GigaOM

StumbleUpon, the social Web service, is doing something pretty cool. No, it’s not going to earn back the $75 million eBay (EBAY) paid for it. But it’s going to start overlaying the information its members have provided about a Web page — whether they like it or don’t, and what they’ve written about it — onto the rest of the web.

StumbleUpon’s product is a toolbar which learns about people’s preferences for Web pages to help them find new ones they’ll like, and the company has collected 100 million ‘thumbs up’ or ‘thumbs down’ for Web pages and 13 million reviewed Web pages over the years.| source: GigaOM

I don't mind. I have quite a few thumbs ups and downs. The premise for many search engines is to help users find sites related to their search terms (keywords and phrases). Why not offer review ratings next to the SERPS?
