Fediverse
Which are the platforms that let you own your data cryptographically and let you move your account around seamlessly for yourself and your followers? Basically the network should be in the data and the servers should be replaceable. I think those are very obvious bottlenecks that affect most of these alternative networks.<p>On the other side, censorship is also very important, nobody wants to have to dwell into spam and filth to read a small amount of valuable content. Maybe be able to choose your own censors somehow? Or build chains of trusts with your friends and "friends-of-friends" that can be revoked at any point?
