My problem with SO (does not affect other Stack Exchange sites) is that the more experience I gain in programming, the more I find more efficient ways to solve my problem (read the spec/source code), therefore less use cases I have for SO. Additionally, isn't the goal of a site like SO is to finally answer every programming question? It is not an insurmountable task if you disallow opinionated questions and be strict about duplicates. I feel like it serves its purpose well and will be a valuable resource for years to come.
