Thinking about this federated stuff...
I think we are almost there to go back to a fantastic source of how the internet used to work.
With Mastodon and Pixelfed, you basically can host your own TW and IG and share across systems. Blogs are already federated, but using Mastodon threads as comments sounds interesting.
Need FB, diaspora and friendica aren't quite there. Video (PeerTube) and audio (FunkWhale) are going to be hard to spread due to server storage costs.
The social network of the future: No ads, no corporate surveillance, ethical design, and decentralization! Own your data with Mastodon!
