Penny Arcade, for those unfamiliar, is a webcomic. It's more than a webcomic, though. It's a franchise, almost. They get commissioned for their art, mostly for big-name games. They have a convention and trade show (PAX), merch, an office and twelve workers.
But they came from nothing. They were just two assholes, sharing a room and working shitty minimum wage jobs who put up comics three times a week to comment on the games they played. Eventually, they got noticed for being smart and artistically talented. The writing was awesome. People started to advertise, and they went from being bums, to being able to sustain themselves, their families, twelve employees, and a yearly convention mostly on ad revenue. If that isn't a triumph of a free market...
I mean, these guys took raw talent, marketed it, used it to create something huge. No government assistance that I know of. No help. Just opportunity. They took opportunity and passion for games, and turned it into fat stacks. They took nothing but that. It's inspiring. I mean, if they can do it, I can.
