If you want to bootstrap a peer to peer network, you can’t start with the mainstream use case. You need to start with the highest value use case, even if it is a much smaller niche.

The same is true of Snapchat. People made fun of Snapchat in its early days for being a “sexting” app. That was the “high value niche use case” that bootstrapped the network. And once critical mass was reached, the broader use case of a network for ephemeral photo/video sharing could emerge.

if you want to build a peer to peer network, you have to find the use case that is high enough value that some people will do things (like put content into your application) that most people won’t. If you nail that, and win the hearts and minds and activity of that small high value user base, then you will have to opportunity to go mainstream.
