A Q&A site like Quora, with more “facts”, and even fewer “non-facts” (e.g. less sociability)?
Stack Exchange. Quite Savage in its culture of Just The Facts, but overall very reputable, aggressively moderated by its users, and its programming forum Stack Overflow is the canonical place for programmers to go for advice.
“So if you hate Quora so much, why don’t you go there?”
Because it’s Quite Savage in its culture of Just The Facts. I stay here because, the best efforts of Quora’s UX team notwithstanding, it is still possible to socialise here.
