There's an interesting discussion going on over on the forums about whether or not Blizzard should conduct player polls. Antiquity from Lightning's Blade can't see why they don't-- it's an easy way for them to get quick feedback about different aspects of gameplay. But Nethaera disagrees. She says (and I can see her point as well) that polls are commonly inaccurate, which is definitely true, and while she doesn't exactly come out and say it, she seems to be implying that Blizzard would rather hear player feedback in terms of discussion rather than in numbers. Just hearing that 70% of players will use voice chat doesn't tell the whole story-- more important to know would be the reasons players would use voice chat, and in what situations they would use it.
So it's not really likely that Blizzard will implement in-game polling anytime soon-- for now, they're content to get their player feedback from the forums (and, I suspect, from sites just like this one).
However. We here at WoW Insider have no such compunctions, and we love to hear your feedback in terms of numbers just as much as in the comments. And I especially like Antiquity's poll suggestion, so here it is. Yes, this isn't really a solution to what he wants-- he wants to hear in-game voices, not forum voices or WoW Insider reader voices. But it is an interesting question, and I would like to see what you all think.
(I did leave off the "All of the above" choice-- if that was on there, I don't see why everyone wouldn't choose it. This way, you're forced to choose your preference.)
