I Don't Have Anything To Offer This "Debate" Except Wisecracks
If you're interested in the kinds of things that professionals and commentarians discuss via e-mail, twitter, Facebook commentary threads and in my case a part of an actual phone conversation, you can read Calista Brill on "When To Give Up" here and Chris Butcher's summary posting that touches on the Internet arguments that followed here.
I don't mean to suggest that the idea of vocation in comics isn't one worth discussing. It's more that I think there's a place for what Brill is arguing, and a place for the reaction from artists and others that don't believe the piece was argued effectively and are worried about some the ideas being floated. It's a "there it is" subject for me. So: there it is.
