I'm intrigued by the idea of a decentralized platform like Mastodon, but all in all I think the federated structure is a failure in practice. It comes in two extremes: acrimonious, censorious groupthink on the one end, and on the other end a torrent of spam 'n porn.

MySpace of old, & early Facebook is a better model: one-to-one symmetric connections, with no activity feed at all, not even a chronological one. Private group chats are also good. The keys are privacy, small scale, & either natural conversation patterns or long-form text. All these things are so much healthier, happier, & more fun.

In short, I'm outta here. I wish you all the best.
