They also don't have the luxury of treating it like a hobby business, which is why they've been focused on quantity over quality for years now. They have to scale up the concept massively or find another business.
In contrast WikiHow is an example of a successful knowledge service that is operated with more of a focus on quality and less on quantity. They're not owned by venture capital firms and don't have to seek an exit or try to force growth at any cost. It's a route Quora could have taken if it weren't for the VC firms, now they have no choice. Their former competitor, eHow, took the paid spam content route and got destroyed for it.

Yahoo Answers might be similar, sure, but that's not a positive comparison.
The second is a matter of opinion, and whether you're looking at the average content or the best content. There is great content on Quora but the average question/answer is of course absolute dogshit.
