The internet's self-conscious act of intellectual validity and authority. Unsurprisingly primarily self-centered and authoritarian instead of rational.
Some of the more objective or positive entries might at first make one assume that most people there are not just as insufferable as anywhere else and like any community on the internet, albeit maybe at the same time with an even more all-encompassing entitlement and smug self-satisfaction.
And assume that the triviality of most of the questions would be self-aware and not lost on most of the people.

Highly restrictive, not only in the artificial question and answer format, but also the ultra-strict length limitations and rampant auto-correct functions, Content Review and straightforward censorship.

Moderation is more concerned with keeping up appearances than with moral tasks, consistency and transparency. Sanctimonious, arrogant, prejudiced and irrational and with a cult-like devotion to their brand and policy taken literally and subjectively.

Actual psychopaths, either self-proclaimed in order to effectively show off or those whose practices are harboured there, are the hipsters of the place.

A once respected website for sharing knowledge that is now filled with pro-Chinese propaganda, insecure Indians, and pseudo-intellectuals with fake university degrees.

A Q&A website devoted to far-left propaganda, extreme atheism, and hating all Republicans, Christians, and anyone who is not a feminist. The site is a raging cesspool of self-proclaimed intellectuals who believe thesaurus-abuse makes them sound smart. Quora is a place with extremely restrictive moderation; in other words, they censor the shit out of anyone who they don't agree with. As Quora moderators have the power to remove questions, delete and edit answers, and delete users entirely, a Quora has developed a culture of deleting and censoring anyone who does not agree with the herd.

The site is a breeding ground for prententious assholes to brag about how high their IQ is and how many college classes they've taken. The result is a gigantic pissing contest of self-centered IQ worship and a competition for who has the most credentials, and anyone who has an opinion but didn't go to MIT or Harvard for 12 years gets downvoted into oblivion and censored by the moderators for not being intellectual enough.

Site full of left-wing nuts who scream "patriarchy" if you disagree with a woman.

The habitat of the social justice warriors.

A place where pseudointellectual moderators ban people to promote their hypocritically anti-intellectual censorship and to promote their anti-white, anti-Christian, anti-men, pro-Muslim, pro-feminism, and pro-LGBTQ hypocrisy because Quora is controlled by out-of-touch snowflakes who prevent brutal honesty and brutal reality.

A tight knit community of galaxy brains. The type of community to seriously consider the Urban Dictionary definition of Quora with the same approach the UB entries mocked them for.
