follow != endorse, I follow many people with all sorts of political, social, religious, etc views, many of which are in strong disagreement with each other and mine, because I like being exposed to all ideas.
Where do I sign up? How do I make an account? Do I need an email? Why are my messages not sending? Why can my friend see my IP address? etc etc it's a terrible protocol. sure you can do it but why the fuck would I want to when I have a dozen easier options.
