No doubt. I must agree with the others who've said that I find the various "medley" options a little hard to distinguish in the poll. I also wonder to what extent the "generic" monsters of the older editions count as "Greyhawk". Certainly that's a factor that's diminished over time, but still relevant even into the 2e era (where it got worse as critters that were originally from FR or DL adventures started to work their way into general usage.)
I read the poll as referring to setting elements, not monsters, classes, or other mechanical elements. My interpretation:
Homebrew Hybrid: Homebrew setting includes the "Moonshai Isles" and Castle Ravenloft. (Drew your own map; copied some names)
The Medley: Ninjas can sail to Lankhmar, just south of the Nyr Dyv, from Zakhara; the Sea of Dust is known as Anauroch; the Red Wizards (agents of the Alphatian Empire) are rivals of the Scarlet Brotherhood (agents of Patera/Myoshima). (cut and paste, literally.)
Published Hybrid: Forgotten Realms, but Ravenloft and a number of other domains replace Narfell and Damara; campaigns center around Impiltur, the Great Dales, and the Dominions of The Raven. (This part of the map is wrong; this is what's really there.)
Published: Forgotten Realms, but no Elminster or Drizzt Do'Urden; previous campaigns/player actions have created a homebrew country south of Evereska. (Pencil in some new names and roads.)
PAW: Played through the Time of Troubles or Fate of Istus; sucked to be the half-orc assassin character. Elminster lives in Shadowdale. (map is laminated and mounted on the wall; a pointy post-it indicated party location; ruler and /or clear hex overlays handy for determining travel times.)
