Dominic is often offline, but he's still able to use a social network to communicate with his friends such as James Halliday (a.k.a. substack), who is also often offline. James has also authored hundreds of npm modules, such as Browserify, and is building his own shack on top of 300-year old lava flows in Hawaii.
Dominic and James are a few key figures in a community of eccentric open source hackers gathering in a social network independent from mainstream internet. The unique properties of Secure Scuttlebutt (SSB) make it possible for digital information to spread easily even in the absence of Internet Service Providers (ISP) and the internet's backbone. What makes that possible is a decentralized protocol based on the mechanics of word of mouth.
