What killed Quora for me was that they decided to prioritize quantity of questions over quality of questions, and as I recall, they even set up incentive programs to reward people for asking as many questions as possible. The site was inundated with repetitive low-effort questions, often with false premises that seemed intentionally crafted to provoke people. The crappy questions drowned out the interesting ones that had previously made me a regular visitor.
