Both of the points you have made are very similar to the issues with ExpertsExchange which SO set out to replace. The reason idiotic questions and answers remain is that they are fodder for people arriving from search engines. If you cleaned them up and removed the duplication there would be a huge reduction in content. I often wonder if Quora actually knows what it wants to be when it grows up. They have some serious funding (https://www.crunchbase.com/organization/quora https://www.crunchbase.com/organization/quora) for what little they seem to have delivered. I would love for them to prove me wrong as I think there is space for an alternative to SO and the StackExchange network.
