Exactly. The kinds of transactions that take place by the thousands (just guessing, might be off by an order of magnitude or two?) on a daily basis on AirBnB, i.e. guests giving complete strangers money over the internet in advance to stay in their homes, and hosts inviting complete strangers over the internet into their homes in the first place, simply has no chance of ever becoming mainstream on a platform like Craigslist. This is precisely because they're the kinds of transactions that most people would never even consider to take part in without first being able to establish a certain level of trust in the other party. I think this is probably the biggest competitive advantage for AirBnB against challengers in the space. Bootstrapping a 2-sided marketplace is hard enough to begin with, but doing so while building up a network of trust among users so they can comfortably partake in transactions with a high trust-barrier is even harder.
