I suspect this would work for games run over the 'net and not in person.
But, for my campaign:
I doubt I'd pay for it, outside of bribing my friends with dinner or something. Most of them are codemonkeys, three of them are artists, and outside of hosting and building the page, I'd feel comfortable providing the content with fiction, storyhour(s), writeups of NPCs, history of various objects, persons, or places in the game(s).
