So AT&T isn't decentralized? I'm not an AT&T customer, nor do I live in the states, but I assume AT&T is a a decentralized network which uses a communications model or let's call it a "protocol" to talk to other networks. If you tell me AT&T is centralized because it's covering a country, or that you can call all your family and never leave AT&T's network, that doesn't mean it's centralized per-se, it might be centralized for it's own services, which makes sense for any company. But it's still part of a decentralized network of communication providers, which use a protocol... A live one actually, kind of like what twitter could become a king node of (after all, the celebrities are there, right?). Oh... I see what you meant, I might have misread that whole post!
