Other services both centralize identity AND algorithms/operations.
This seems to centralize identity WITHOUT the second thing, which strikes me as the worst of both worlds.
It's just, we've already mostly "solved" the centralized identity problem with EMAIL. As often, the key is "fail elegantly," not be bulletproof. Email, in it's federated state, allows for individuals to more or less choose what kind of centralization they want -- and more importantly, to kill and restart accounts if needed. Thus, Mastodon is the best parallel.
What am I missing? What is the advantage of bluesky here?
