I guess what I found interesting is that this was something MILLIONS loved and yet it was a very specific demographic so the wider world missed the potential.

Heck, most people, if you pitch them on Airbnb today, will say: "That would never work". Half the people I know outside the tech niche haven't heard of it.

So something can be quite large, well proven, yet seem like a lousy idea if you have a set of blinders on.
