Ask Jeeves just launched Web Answers, a service similar to Google Q&A that tries to isolate the direct answer to a query from the other text in the page. For example, the first search result on Ask for "Who is the CEO of Amazon.com?" is a Web Answer.
Like Google Q&A, coverage is poor, but I would expect this to improve with time.
I find these attempts to extract answers from web pages fascinating. It's an early step on the long road toward understanding the vastness of knowledge stored in the Web.
