Currently, less than half of the questions on the "Newest Questions" page have an accepted answer, although most of them actually do have answers. This question for example didn't get any activity in the last days but has two answers with upvotes, the higher-voted one even seems to address all points in the question.
My question is: Why are there so few "accepted-answered" questions here compared to e.g. SO, where > 75% of questions have an accept within the first few days? One point might be the far lower number of users here, but I feel that some askers might not know (or care) about accepting. Maybe we don't force the Q&A-format enough?
