Since all votes have the same weight I guess it makes sense that the answers to most basic questions or highly common problems will get the most points. Maybe SO should have a button to donate points to an answer that really saved your bacon, a super-upvote if you will. (I know you can attach bounties to questions, but that's not really feasibly when you come across something that has already been answered).
But yeah, crowd behavior is fun. I have the feeling I can time when some computer vision courses (or the semester) starts, as suddenly there's many upvotes on my basic answer explaining BGR/RGB color space confusion with OpenCV, the computer vision library :)
