The guy that runs Craigslist is a real one. He could be charging for the whole site, but he isn't. He could put ads on it, but he isn't. He makes enough money for himself and his employees to live comfortably and keeps the website the same on principle. It really pisses me off that people abandoned it in favor the evil that is Facebook. Support the good ones, like Craigslist and Arizona ice tea, reject the evil ones. It's simple.
