* here's a piece on another show that fell well short of being able to pay its media guests. I don't know that I'd do any show that didn't pay in advance right now. That said, people are still launching comics shows. I think it's the low threshold for participating with something like that, the thing that makes it attractive as a business venture.
* I've been going to SDCC since 1995 and last year I got so confused as to how to register I basically went to the show's organizers and surrendered. I bet the uncertainty of its entry points has a a huge effect on how the show is perceived.
