What I mean by "It doesn't matter" is as far as the mechanics of the next edition are concerned. If what is said here has no impact on WotC's decisions, then all it accomplishes is at best wasting time and engaging in wishful thinking/speculation; at worst it accomplishes poisoning the well. Therefore most of the discussion is pointless to begin with. And if it's pointless, then the only thing that can come out is a net loss.
Where do you get "what is said here has no impact on WotC's decisions?" If WotC is soliciting community feedback, then the tenor of the community affects that feedback. Moreover, if WotC people are reading ENWorld threads (and we know they have done in the past), what is said in those threads may influence their thinking and hence their decisions.
No, Wizards is never going to say "The poll on ENWorld says we should embrace the d17! Guess we'd better call up the folks at Chessex and tell 'em to get cracking." But indirect influence is still influence.
