> I keep running
https://communick.com because I am stubborn and because I can afford to, but honestly I've pretty much have given up hope that the basic services (Mastodon, Matrix) will ever reach enough users to be able to pay for themselves.
I have a faint hope that mobile hardware, software, and networking may eventually improve enough that federated communication nodes could run directly off the clients themselves.
The technical requirements are far from impossible - without even going for a Linux phone, you can run a nginx web server on Android via termux, and use dynamic DNS and/or IPv6 to stay discoverable as you move through cell networks. And hardware-wise, the power is plentiful, although I don't know how bad the battery drain would be.
But of course the experience has to be as easy as click link -> install Mastodon app -> have your own instance running off your device, with nothing but a subdomain in the cloud. Anything less and it's a non-starter.
