The accepted answer is often wrong (or obsolete) and grants a small number of points. The obsession with it on SO is a bit odd.

Yeah I tend to think if another answer has double the points of an accepted answer, that answer should come first.

Plus, often there is a decent and accepted answer given quickly and then a much more complete answer given later on that is really the one that should be considered in the archive.

In the vast majority of cases the accepted answer is the most upvoted answer http://meta.stackexchange.com/questions/178439/can-we-exempt...

But then again: the most upvoted answer doesn't mean that it is the most correct (whatever it means) one. Though likely it is.
