Me again. I've been in the VLQ queue (also again), and I've seen a rash of answers which are posted without anything to back them up. That's to be expected. The backing up policy is relatively new; it's going to take some time for that to become standard behavior.
Except I've noticed that many of these answers had been posted within 1 or 2 hours of me seeing it. Since then, someone had left a comment asking them to back it up, and presumably flagged it as low quality (or someone else did).
I feel like this doesn't give a very big windows for users to edit their answers. As I just said, "the backing up policy is relatively new; it's going to take some time for that to become standard behavior".
It seems that while we're working this policy out, there's going to be high volume of users who post answers they thought were ok, only to come back a few hours later and see it deleted. That would discourage me.
Is there any merit in trying, as a community, to hold off for a few hours before closing an answer on the basis that it isn't backed up?
I assume there would be headaches in cracking down on it even further down the road ("Can we start quickly enforcing the 'back it up' policy"), but there are also headaches in removing answers that a user was ready to improve.
