The problem is that any "Q & A" site is great when is new because it's empty so all Questions get answered, as soon as you are not asking anymore, just looking for previews answers its not a Q&A experience anymore.

One solution for this sites would be to purge old answers or encourage repeated questions, I can support that because there are always new users eager to answers those repeated questions.

But what's the point of answering already answered questions except to get new users more reputation?

Luckily for those new users there will always be new programming languages, libraries and problems.

I don't really understand the point of that. The Q&A experience still exists, you just have to ask the search engine first, then a human if the search engine doesn't help.

The important things about a Q&A knowledge base is that the answers to real questions are persisted. This means that one answer can serve many askers.
