Exactly that false sense. I 've never used airbnb, but reading the positive hype i would be very positively biased to use it, while i would think Craigslist is "creepy". It's a matter of overinflated hype here more than anything else I think. With great hype, comes great responsibility, a wise man once said.
Website more pretty. They also have an intro video with a lady talking. Craiglist does not have a pretty site or video with a lady talking.
