StumbleUpon, a fun Web discovery service, is getting a new feature, SearchReviews:

“We’re really excited about this announcement. We’ve been hearing great feedback from you about our SearchReviews feature that has been in beta, and allows you to see StumbleUpon ratings layered on your searches on the major engines - Google, Yahoo, Ask & more. This feature helps you discover great websites whether you are pressing the Stumble button or searching the web. Today we are officially launching SearchReviews for both Firefox and Internet Explorer, and announcing some really cool enhancements. ”
