I looked in the FAQs section and searched, but maybe I'm missing it.

I've noticed a lot of questions that have great answers that have been voted up 5-20 times for the answer, but the original questioner has never accepted an answer in the question.

Does this just remain this way or is there an automated process to eventually auto-select the answer with the most up votes?

Or does an accepted answer really not matter overall?
