I agree. I think it would make more sense to just have discussions about whichever of the topics interested people, rather than having a fixed poll. If there were such a poll, it should be one designed to encourage 'other' views and frequent revisions of one's view.

I might make something like this at some point, if only as a pedagogical tool or conversation-starter. At the moment, I have good introductions and links explaining all the PhilPapers questions up here.
