What I've learned about Quora from this link is that the highest voted answer (currently) is historical hearsay, when an answer with half the points is based on actual, first-hand experience.
This happens on every moderated forum all the time, including HN. I've learned to get over the idea that the most correct answer will be moderated highest. One reason is that the righter answer might have been posted later. Another is that a less right answer might have been written in a more entertaining or attention-grabbing way.
If you want a HN example, take my post on "Google's Android faces a serious Linux copyright issue."
It was moderated 8, and contains the precise answer to the issue/controversy (it quotes the exception from Linux's COPYING file that both LWN and Linus himself cited later to refute the alleged "copyright issue")
The highest-voted comment on the article (38) does not mention this exception, and is full of inaccuracies like "Unless these programs are actually copying parts of the kernel into their source, they are not derived works."
