It seems to be the AirBnB's effort to build more and more community into the platform puts the business at odds with its ultimate growth driver (replacing/substituting hotels). This just feels like another step to move the company further away from a hotel-replacement and more towards an online community, which feels more niche.
I'm not sure what the solution is to making hosts feel more comfortable with strangers, but stuff like this just makes me want to use the platform less.
