Zippo: by creating a "cut-off" (of ANY year), that would make a great many questions, which are JUST FINE, disappear/be invalid due to an arbitrary timeline. I'm sorry, but I really do NOT agree that everything prior to xxx date should be rendered useless/unacceptable. Sure, there are SOME q's (hardly the majority) that are outdated or perhaps incorrect, but that's what the correction notice vehicle is for.
As much as I love my friends, I won't jump off a bridge WITH them. Instead, I think it's in our mutual interest for one of us to try to catch the other when they fall.
