If Andrew Warner told the world that Airbnb does things that don’t scale, and succeed with a big scale (have you heard of their $1billion valuation?), I, just one individual airbnb user, had a full taste of how they actually execute on that idea (don’t scale) and make the process look so easy.
This sentence makes my head hurt. I don't understand how they do things that don't scale. Seems perfectly scalable to me.
