What is ActivityPub, and how will it change the internet?
The idea that you should be able to shield or blind yourself to content is a flat out stupid one. Not to mention that the way Mastodon works kinda lends it self to the old issue of jerk forum admins. If an instance owner doesn't like what you say for any reason they boot you off. They can also share that information with other instances to block you from going to those instances as well. Sure, you could start your own or join an instance that doesn't do that kinda stuff, but then what's the point of federation?Those are really the only two issues I have with Mastodon.
