it's probably too late now to change it without ...

Yes. I asked because my mind drew a blank on intermediate options between some problem and none. I interpreted some problem as being intermediate between problem and no problem.

"It's possible that a huge influx of new users might make things worse in these ways, or that it's already doing so, and I'm certainly not prepared to state flatly that neither is the case, but I also don't see any grounds for calling it likely or for getting very worried about it at this point."

Ok, so your suggested option would be (to make sure I understand) something like "I'm not convinced either way that there's a problem or that there's no problem).

Maybe what you wanted was more of a "What probability of a problem is there?" not "Is there a problem or not, is it severe or mild?"

Don't know how I would have combined probability, severity and urgency into the same question, but that would have been cool.

I'd thought there was a workaround by making a series of single-option multiple-choice polls

I considered that (before knowing about the two options requirement) but (in addition to the other two concerns) that would make the poll really long and full of repetition and I was trying to be as concise as possible because my instinct is to be verbose but I realize I'm doing a meta thread and that's not really appreciated on meta threads.

Epiphany, I see you got downvoted. For the avoidance of doubt, it wasn't by me.

Oh, thank you. (:
