These middle entries ("Favorite X") really aren't that thought provoking. The best topics are toward the beginning and the end of the list.
Where I to make a list, it'd have stuff like:
Greyhawk: how a campaign should be published or just an old antique?
Elminster: should he live or die?
Do you allow Monty Python quotes at the tabletop? Why or why not?
Why to you love/hate/feel indifferent to 4e?
Is your character drunk yet?
Is D&D Next D&D last?
Do you spend more time talking/posting about gaming than actualy playing?
How do you kill a flumph?
What were the last words of your last character who died?
Do you think you're addicted to D&D?
