good observation. It's worth posting because the dude (Craigslist) is A) the anti-pattern to those who say the only way after you get big is to advertise (missing the point you annoy your users beyond distraction) and B) nobody believes (and probably why its a story) that Craigslist has not sold out and pursued the megabucks that could cough be made with greater advertising.
