I'm not sure what's hard to get exactly. How would you like it if Google forced you to sign in to search and then one day told the whole world what you were searching for? Yes they backtracked on the latter but it's fucking ridiculous that it would have even went live in the first place. It makes me never want to sign in to Quora again. And since you can't even browse the site effectively without signing in, the whole thing is useless.
Like Facebook, it's a great product created by people who have made some questionable privacy decisions. However whenever Facebook is discussed on HN 95% of the comments are not negative.
I'm not saying Quora is perfect and above criticism, but there are a lot of great things about it and its not so bad as to warrant the extreme and near-absolute criticism it gets on HN.
The fact that they have to monetize hurts their user experience because they push features such as requiring you to sign to view answers.
As long as Quaora continues to hide content, in long term, there is no way but bankruptcy.
Which opened the field wide for StackOverflow to come in and succeed.
Is there any reason why a similar replacement for Quora can't take off?
