How to deal with obsolete answers?
I wonder if one final goal of the Stack (that is, to have all-the-time the best answer on the top of the list, even when technology changes) is actually reach from time to time.
Let's say that there is a very funny-weird bug in framework "X", which is clearly explained in an answer which has been up-voted a lot.
Then the framework is fixed by the editor.
The "community" should vote this top answer down and/or should make the "new" best answer (that is "there is no such problem anymore since release xx.xx") going to the top.
But my point is that this particular question won't attract any users anymore, because it has a lot of answers, and one has been voted "the good one". So it's like this "now-wrong" answer will be the best forever.
I'm think about a new feature like "this-is-not-the-good-answer-anymore" button. This will "clean" the status of the answers posted. All this to attract users and focus the gurus of that technology domain on that very question.
Joel? Jeff? What's your opinion on that? (Should have been a podcast user question, isn't it?) I hope I'll get a ton of reputation with that (and a free t-shirt).
