I haven't used AirBnB, but was considering using them in the near future for travel, and possibly to try to reduce losses on my bachelor pad (until I hit the end of my lease).

While the current incident doesn't make me feel unsafe in those choices (statistics are good), AirBnB's handling of it has left me with no confidence whatsoever that they are a well-managed or reasonable company. They may well be awesome people... but they do have competition, and I'll be using them instead. First impressions matter.
