    It’s the same reason there isn’t a central email sign on. Different people control different servers. They’re all just using the same protocol so they are interoperable. Just like your email, you have an address that points to your particular account on your particular provider. [email protected]. It’s essentially the same thing as email, just a different form of interaction.
