Well, I find the poll results interesting because literally the only people I know of that still play 3.5 are people I know from EN World.
None of the local gamers I know still plays 3.5. That not only includes my immediate group which is 9 people (none of whom read EN World), but also the people I know from hanging out at the FLGS who all have their own groups that play 4e. All told, thats around 30 some people, probably more. All 4e only with zero interest of going back to 3.5. And we talk about this stuff all the time.
Heck, my FLGS doesn't even stock 3.5 books or Pathfinder stuff anymore outside of a token copy of the latest release. The owners will order it for you if you want it, but it doesn't seem to sell well. But that could also be because all the Paizo diehards all buy based off subscription or internet sales direct from Paizo.
Anyway, I think EN World's audience seems to skew heavily towards 3.5 and Pathfinder fans. The poll results don't mesh at all with the reality I see offline.
