I think one of the things that makes twitter successful is it's lack of features. I'm on friendfeed, I was on Pownce, neither of them stuck. Friendfeed comes across like a 64-track mixing console with a builtin patch bay; it's got features and it does stuff. It feels like Pro Gear, but it's mostly built for readers not senders. Twitter is as close as my phone. It removes most of the barriers to publishing, and the limitations help to make it predictable. Could twitter's functionality be replicated; yes. However none of the fast followers seem to be able to stick with the simple feature set.
