Quora used to be good before 2012-13(?), what with its credit system and all. You had a fixed pool of points to ask questions. Potential people who wanted people to ask them questions could arbitrarily set their points, and these points were deducted from questioner's pool, and added to the answerer's pool.
When this was removed, it was the beginning of the end. Clickbait, self-promotion, rabid people-centric cults, unrelated answers (no person X, you should not answer with a sob story for 'what's the weather like in Seattle these days?'), no question details allowed, answers catering to the lowest denominator, crappy feeds, and (imo) the worst - fabricating actual relationships, sob stories, and credentials (IIT/MIT/etc.) to garner more views and become a top writer (w/e that's worth).
And the rabid and toxic community is nauseous, to say the least. No enforcement of community standards means that every non-mainstream opinion (or even an opinion that goes against the Quora mainstream) is lambasted as if you had insulted the commenter's family.
Although HN's moderation policy may seem caged to some, it is the reason for the quality of the community's discussions. Quora is a textbook example of what happens when users are given freedom to do whatever they want to. It is the reason why I deleted my Quora account happily (even though I had 1M+ views on my answers, and I liked answering the most mundane of questions) - the site is not worth the time you devote to it.
