Well put. There is actually a major difference between a joke thread here and a joke thread on Stack Overflow: on HN, it would be on the front page for a few hours or perhaps a day at most (less if the volume of comments triggered the anti-flamewar code). But on Stack Overflow, the joke thread was being bumped to the front page every day for months; any edit or new answer jumps it to the top again, even if that answer is a copy of six other answers.
