What bothers me more is that Craigslist is one of the great Silicon Valley stories of something that grew from nothing (an email list that one person created). They weren't always big. Long ago they were a small, scrappy startup. It took years of perseverance, hard work and providing a useful service.

It's a story startups should aspire to. Instead AirBnb seems to get a pass because they are a YC company. I can't wait for irony to strike when another startup does this to AirBnb.
