Agreed, it was great.
For the record, I haven't perma-quit, but I am in a state of indefinite hiatus that may or may not end at some point.
Mostly, DYOS 12's plot has been enough of a mess that I don't see myself having much to add to it, nor do I really have any motivation to add to it. I would like to finish 10.5 at some point but everyone else seems to have abandoned it.
Well that and G-Mod broke something every time it updated and I eventually just got tired of trying to make comics in it, C+P and horsehockey paint comics seem too laxy and minimalist to really work for me these days, and I couldn't draw a decent anything if my life depended on it.
And I keep ending up with more things to do IRL.
