I think it would be a bit of a Catch-22. Since the poll is “about this message board” it wouldn’t be appropriate for IMHO, so if it was reposted there it’d have to be moved to ATMB for future closure.
In the poll I posted a little while ago, TubaDiva didn’t actually lock the poll but gave this response:
So I guess the staff see themselves in between a rock and a hard place. Polls in ATMB wouldn’t be binding but they could be embarrassing if they are overwhelmingly pointing to a wish for change that the admins don’t want. I would say that too would be mere pedantry as having the poll numbers isn’t much different than seeing the number of people who typed out a full post to express their opinion.
For example, if this were a poll, I would have voted for “Allow real polls in ATMB” but since it’s not I’ll just type out: I think we should allow real polls in ATMB.
