Introduction A year and a half ago, I wrote about what a federated replacement for Facebook would look like. Part of that was differences from Facebook, and another part was differences from Mastodon, the leading federated social network software. Since then, I’ve used Mastodon a lot more, Mastodon has added and changed features, and my thinking has evolved, so I feel like it’s time to write an update to that article.| jfm.carcosa.net
