Has a microformat been proposed around “Questions and Answers”.I think it would be good to mark a question and the corresponding answer in <span class=qa><span class=question>Where does paul kinlan live?</span><span class=answer>liverpool</span></span> It could help solve some semantic meaning to what part of text is a question and what is the anwser. For instance I get a lot of searches coming to my site with queries such as “How do I…”, “What does…”. I could set up a “search engine” that parses pages with this micro format in and indexes question and answer pairs rather than whole text pages. Is this a good idea? Is it worth progressing? Has it already been discussed?
