Quora – a lot of information is not the same as an answer to your question

Quora is attempting to create a social answer service (I like this description and I think it is original).  It seems similar to Mahalo to me, but the approach taken would appear to draw in more contributors (perhaps of varying quality). I think that the mechanical efficiency of Google search is clearly a great way to find information, but finding answers that require an interpretation must tap into creativity and problem solving best offered by human volunteers. This should be interesting.
