One thing that SO desperately needs is a way to "update" an answer. The correct (or best-practice) way to center a <div> 10 years ago is not the best way to do it now. An easy way to accomplish this would be to weigh upvotes based on how recent they are. More recent = more weight. An answer that's been receiving more votes lately should appear nearer the top than an old answer that received more votes a long time ago.
They already had that feature. Just some questions were only valid at that time, so that the answer doesn't need to update, just leave them there as a historical reference. Some other questions, if you found an other answer recently, be nice and give your answer. If the question's author is still active, he will update the answer flag. Otherwise, users will upvote your answer when they find it useful for them and moderator will base on that to update the answer flag.
That's why, when searching SO for answers, I always look at the dates, and take that into account. A mechanism automatically downgrading outdated answers will be either very sophisticated, or very inaccurate.
And, regrettably, sometimes we have to keep the code compatible with MSIE...
