The fact that you bring up StackOverflow is pretty interesting. I think StackOverflow is a great idea and a great resource, but it also suffers from a lot of issues (especially with how its karma system is implemented). I think this is somewhere Steemit could really shine. Rather than punishing people for asking off-topic/simple questions, they can get an answer and the person being answered can make some money off of it (with upvotes). More relevant questions would be voted highly (which would eliminate the need for downvotes to sort content). Maybe a tag like #steemoverflow would be useful to mark these questions? Either way, having a way to both share solutions to programming questions and make money off of it seems way better than what StackOverflow currently enables.
