At the blog for the comic, they updated with some descriptions of the cast of the series...
Josh Sands: One of the founders of comiccritics.com, Josh is a diehard super hero fan clinging to the fading vestiges of that once mighty genre. He's 23, with a bachelor's degree in Communications that is only slightly less useless than the envelope it still resides in. Just to complete the sad cliche that is his life, Josh works in a small neighborhood comic shop.
Marissa Goldman: Another one of the site's founders, Marissa's interests lean towards independent comics, though she also enjoys poetry and classic literature. She's 25 and works at a Booktopia, a trendy new book store/coffee house franchise that she hates. Marissa is also pursuing an undergraduate degree in American Lit.
Jamal: Little is known about the Comic Critics web designer. And what is known is...unsettling. He's quite technologically adept, and prone to fits of maniacal rage and paranoia. His arch-enemies include balloons and cats.
So far, sounds good to me!
