Oh my God. Drunk Patrick dancing is a must see! (Edit: OMG! He's dancing in that one panel! -squee!-) He better get a hot guy to hook up with, or at least dance with! (I totally bet he loved when Melanie's boyfriends came over XD ) Poor Michelle though... She needs to be drunker.
Having read a lot of comic trades recently, and just regularly reading comics, I have decided WHEN you release yours, I will be disappointed if voting incentive material like alt. dialogue, work-in-progresses, etc. doesn't make the back where variant covers/fluff are (don't forget the fluff either!). Sometimes when the story gets slow, that's what keeps me from just letting a few days build up and just reading a chunk that hopefully has moved on by the end. Plus, I occasionally seem to miss some really good incentives, so another new thing in a familiar package can't hurt sales, right?
Demonic, hate to disappoint you, but stuff like alt dialogues won't appear in print versions. I can't say what kind of extra material would be in them, but I can tell you the alt dialogues won't be. They're nothing more than fun thank-yous to the folks who vote.
And honestly, at this point, the release of print trades is still very much a very big IF.
