Windows Live has launched QnA in beta. It’s a response to Google Answers (which uses paid researchers with community comments ) and Yahoo Answers(which relies on community amateurs). QnA has individual ranking and community features. Meanwhile, MS’ “Live” experiment continues its headlong rush to get competing offerings onto the market. The latest is Live Shopping.

Froogle, in contrast, asks for submissions and as a result has better formatted entries. Techcrunch has the skinny.
