Airbnb's technical quality has been obviously crap for its entire existence. Why are we taking engineering cues from a glorified room rental site that is frequently buggy?
Don't think of it as advice from a crappy site. Think of it as developers at a big company sharing how they do things. Take what you want from it, or just use it as a conversation jumping off point.
I've used AirBnB several times and never found it buggy enough to impair my main objective of booking a place to stay. It seems to be as robust as it needs to be.
