I often see the "Accepted" answer with 2 or 3 points, and then a question below that with 10+ points which has more work put into it over a longer time, so the first answer was a quick solution to fix the asker's question, but other users put work into a better answer and the answerer ends up getting points for that as well. This is great because it creates a fast answer (good thing) and a good answer that takes longer. (also good.)
