Have you noticed the new polling threads? These threads are basically X or Y threads, some of them, literally Choose X or Choose Y. (two options) So I think with this new system it's necessary to modify the rules to suit the forums better.

Say "All poll threads should have five answers". That hurts no one and at the same time holds some value to discuss because there's five options. And really it could be any number! (except one of course)

"5. No 'x or y' threads.
'X or Y' threads have little discussion value and often end up being full of one word posts. Threads in Off Topic are supposed to promote discussion." -From the Off-Topic Information and Guidelines.

What I'm saying is that the X or Y rule is now unnecessary and that if we changed it up a bit, it could only help the forums.
