That's a good idea. I'd also like to see the ability to re-ask questions after a few years without them being dismissed as duplicates. There have been a few questions where the answers no longer worked due to being obsolete, and I had to figure out the new solution myself. And in some cases, the answer never worked properly but was accepted as the best known at the time, and I had one that worked. But there was no point posting, because the accepted answer from X years ago dominated, and it was unlikely that a contribution from little me would be noticed. In fact that's why I never ended up joining SO despite being a heavy user - on each of the occasions I felt I could make a useful contribution, it happened to be a question that was old and "settled", and I felt it wouldn't be worth the effort.
