Quora is far from being the best Q&A system ever (the best was Aardvark, bought and killed by Google) but it provides many interesting clues today. I've found quite a lot of very useful and rather unique information there. It seemed quite dead back in the days I've first tried it (looking for something to replace Aardvark) as nobody would answer my questions but the things seem very different today.
Aah, Aardvark. I answered a few questions on that system, but after a while I felt I was just serving idiots who were too lazy to google the questions.
I enjoyed being one of such idiots and answering other idiots like that. Because I strongly prefer unmoderated, marketing-free opinionated answers based on personal experience/knowledge and expressed in a concise manner to raw web data. I don't even mind googling some details to come up with a clean answer for the others. That's a kind of community I'd love to participate in.
In fact, even when somebody submits a completely just-google-it question you can answer comprehensively by just looking at Wikipedia or the first ling in the search results or something everybody is supposed to know it doesn't irritate me, whenever I can provide a useful answer to somebody's question it floods my brain with dopamine and serotonin so an easy question is just an opportunity to get the reward easily.
Whatever (from a sophisticated scientific question to a rhetoric question/joke) I would ask on Aardvark I would almost immediately receive an interesting answer (better than those you usually find on Quora) to and some more answers during the following hours. That felt so cool. Then my imagination has ran out of questions and then Aardvrk got terminated. Now I know and so much more things and gave so many new questions but there is no Aardvark any more :-(
