No, but almost. First, twitter, unlike facebook, is asymmetric. Therefore, I can follow all my favorite web-celebrities, and they can totally ignore me. Second, because twitter is about more then just the most recent message from that user. It's an aggregation of those messages.<p>I think the real use for twitter comes from either sending out links, or mentioning breaking news (like, for example, tim russert's death, which zipped around twitter long before it broke).<p>In that regard, I think the a more "proper" mental model for twitter isn't so much as aggregated facebook status messages, but more like distributed reddit (except, in a central place... so.. psuedo-distributed?).
