Those answers seem just random guessing?

Yes, it’s a discussion more than anything. I couldn’t find a single well sourced right answer.

You say Quora, I say "Gell-Mann amnesia effect".

In my experience, the percentage of Quora questions that have an actual helpful and correct answer is somewhere in the low single digits.

I never really looked into Quota, do people get paid for answers or something? Half the answers I read seem like someone just compiling random things they found in related Google searches.

From what I read, Quora went through a time when both questions and answers were paid for.

Is there anything better, though?
