I missed the humor.
I think the bottom line here is I certainly wouldn't want old threads to go away, there is a lot of useful information posted. I've even posted some of it.
I personally don't think that reviving old threads is necessarily bad, but I really don't see a prompt saying it's an old thread would be a huge hardship, so I can go either way personally. I'm not sure it's really needed, but who's to say...
