I couldn't book a place the other day because their online booking system was broken. It made me realize why most places and hotels use Booking.com or Airbnb. It's not just about discoverability; getting a booking system to actually work is a really hard problem.

These are things only made possible with web or mobile apps. Booking.com and Airbnb have a combined market cap of around a quarter trillion dollars. That's how valuable a functioning booking system really is.
