Uber at their worst still beats the heck out of taxis at their best. (Yes, that's an exaggeration, but only a mild one.) There is a reason why the taxi industry died almost overnight. Legalities aside, that simply doesn't happen to industries whose customers are happy.

However, I've never quite grokked AirBnB. I'm not a big fan of traveling in general, and when I do travel I prefer (and don't mind paying for) predictability and good customer service. Crashing in some random person's house doesn't seem very predictable, as threads like this tend to suggest, and responsive customer service is obviously out of the question.
