I disagree, quora at the beginning was a place to find quick answers to a lot questions on many different themes, a bit like reddit. But it rapidly became full of "pro replier" just like the Microsoft forums and it was unbearable, then, my 2 cents, it was confusing because of subscription, layout, suggested q&a totally unrelated to the topic I was looking for and a lot of questions that nobody would ever even post on /No Stupid Question (I don't want to judge, but for a lot of them it was easier, faster and you'd get an immediate answer with a plain Google search)
