I'm missing your point. If something deserves a down vote, it needs it now, not six months from now. If it's bad advice or just inflammatory, many eyes will see it and some will respond. A "Best Practice" post which seemed fine two years ago, may be down voted if posted today, but I fail to see the reason why one would hunt it down and down vote it now.
