see this is part of the problem with social networking.

'once your friends start using twitter enough'

it's proprietary and unstandardized, unlike email or phone numbers where it doesn't matter as much what network you are on, you can still make and receive messages. (I know cells are very proprietary, but you can still get calls right?).

That's the thing that bugs me about Twitter.. It's essentially just another walled garden. But that aside, maybe the model is cool, and a good way to follow friends and acquaintances. So is anyone creating open/unwalled pub-sub software that anyone can use on any server for a similar purpose?
