Here is a survey from remnant entertainment for ?Tales of the Unwritten? a commercial mmorpg in early development (as far as I can tell) & they asked this to see what the curently active people want, maybe we should have something like this, I think it would be nice, take a look:
http://www.remnant.com/mmogsurvey.asp(Lets see, a lot of this stuff is already been planned to be implemented or is already in mb or it is about how much you would pay so those are out, but I like the questions about random quests & constantly changing geography such as re-directing rivers & such?)
Edit: I sort of narowed down a section of the servey:
