AT Forums could be experiencing a geezer effect: At forums have been around for a while, so they've had a chance to build up a fairly mature community of regulars who are PC Gaming vets, so to speak. The geezer effect comes into play as mature users and older people in general tend to be rather averse to significant changes in the way things are done. At the ripe old age of 25, I'm already started to feel that way (those damn kids and their damn digital distribution, I remember when I was a kid you OWNED what you bought with the lunch money you saved! *waves cane*)
These same people, the regulars, are the ones most likely to vote in this poll, since anyone else is probably stopping by to get some GPU hiccup resolved, potentially skewing the results in favor of the "NO" answer choice.
I've taken the liberty to post IDC's original post verbatim (along with topic title) to some other, less "hardcore" PC gaming sites for some spectral analysis (GameFaqs, for example).
I will post some results when I have them.
