@atomicpoet @matt Yes, but for those that don't have constant access to the internet (or any access at all) use more primitve means to move information: sneakernet, mesh networks, etc.
Sneakernet on it's own isn't reliable (interception, changing messages, etc.)
Hopefully SSB won't remain unmaintained. The Fediverse is cool and all, but only available if you have internet access. SSB can work when no electronic network at all is available.
