Wikipedia is useful, no denying that. StackOverflow might as well just be put into read-only mode at this point. Asking new questions is more likely than not going to end up with your question locked for some reason. It's a super useful archive of questions and answers from back in the day when they still let people ask questions, but as far as I can tell no new useful content is being added. A few of the stack exchange sites are still allowing questions, but on the programming one the "ask a question" button is just a decoy.
