> What does Twitter do so we’ll that we can’t imagine doing without it?
It's a place that media whores love, and they're the ones who make all of the content. That's why we're hearing about it endlessly. One of the biggest media whores bought it, so it should really be considered an internal war that we're just bystanders to.

I'm pretty sure that what we wanted was to be able to send public text messages that people could subscribe to, and to be able to subscribe to other people doing the same thing. Putting the right UI over group chats, and making every registered user a mod of a group chat that shares their account name would be Twitter-- i.e. an ideal replacement.
