Well, probably another sad fact is that Dan Slott isn't going to sell a comic as well as someone like Wheadon or Bendis. Marvel doesn't sell Slott like they should. And, since Slott hasn't done the big name books, like X-Men, he's more a fan favorite of select little groups, like ours.
(Now, one thing Slott does have for him, I would bet that we'd pop over to DC if he ever jumped ship, more than anyone else Marvel currently has working for them. Hmmm...Slott on Captain Carrot and the Zoo Crew...I'd buy it.)
