Yahoo Answers has terrible answers. Reddit is full of trolls. HN is technology only and requires a lot of effort to get attention, most submissions die at one or two points. StackExchange's model is great for technical and highly specific questions, but its approach doesn't work well for the sort of questions Quora does.
Where else on the internet can you ask and get great responses to these questions?
