Scenario by example: A question on stackoverflow.com was changed entirely within minutes of its posting, invalidating about five responses to it.
What is the community voting policy on the original question? Voting has evened out at 1 upvote at the moment, but the question netted the poster a solid amount of negative votes, too.
I'll be honest: I'm surprised about the upvotes. That being said, I haven't voted yet (my daily cap is already exhausted, even if I wanted to), and was wondering what community policy is, if there is such a thing as accepted etiquette on this subject.
