I was warming to my subject now, in that flow state that great athletes get into when they just know where to swing their bat, where to plant their foot. I knew that I was working up a great rant.

"Fast-forward to the age of email. Slowly but surely, we begin to mediate almost all of our communication over networks. Why walk down the hallway to ask a coworker a question, when you can just send email? You don't need to interrupt them, and you can keep going on your own projects, and if you forget the answer, you can just open the message again and look at the response. There're all kinds of ways to interact with our friends over the network: we can play hallucinogenic games, chat, send pictures, code, music, funny articles, metric fuckloads of porn... The interaction is high-quality! Sure, you gain three pounds every year you spend behind the desk instead of walking down the hall to ask your buddy where he wants to go for lunch, but that's a small price to pay.

"So you're a fish out of water. You live in Arizona, but you're sixteen years old and all your neighbors are eighty-five, and you get ten billion channels of media on your desktop. All the good stuff-everything that tickles you-comes out of some clique of hyperurban club-kids in South Philly. They're making cool art, music, clothes. You read their mailing lists and you can tell that they're exactly the kind of people who'd really appreciate you for who you are. In the old days, you'd pack your bags and hitchhike across the country and move to your community. But you're sixteen, and that's a pretty scary step.

"Why move? These kids live online. At lunch, before school, and all night, they're comming in, talking trash, sending around photos, chatting. Online, you can be a peer. You can hop into these discussions, play the games, chord with one hand while chatting up some hottie a couple thousand miles away.

"Only you can't. You can't, because they chat at seven AM while they're getting ready for school. They chat at five PM, while they're working on their homework. Their late nights end at three AM. But those are their local times, not yours. If you get up at seven, they're already at school, 'cause it's ten there.

"So you start to f with your sleep schedule. You get up at four AM so you can chat with your friends. You go to bed at nine, 'cause that's when they go to bed. Used to be that it was stock brokers and journos and factory workers who did that kind of thing, but now it's anyone who doesn't fit in. The geniuses and lunatics to whom the local doctrine tastes wrong. They choose their peers based on similarity, not geography, and they keep themselves awake at the same time as them. But you need to make some nod to localness, too-gotta be at work with everyone else, gotta get to the bank when it's open, gotta buy your groceries. You end up hardly sleeping at all, you end up sneaking naps in the middle of the day, or after dinner, trying to reconcile biological imperatives with cultural ones. Needless to say, that alienates you even further from the folks at home, and drives you more and more into the arms of your online peers of choice.

"So you get the Tribes. People all over the world who are really secret agents for some other time zone, some other way of looking at the world, some other zeitgeist. Unlike other tribes, you can change allegiance by doing nothing more that resetting your alarm clock. Like any tribe, they are primarily loyal to each other, and anyone outside of the tribe is only mostly human. That may sound extreme, but this is what it comes down to.

"Tribes are agendas. Aesthetics. Ethos. Traditions. Ways of getting things done. They're competitive. They may not all be based on time-zones. There are knitting Tribes and vampire fan-fiction Tribes and Christian rock tribes, but they've always existed. Mostly, these tribes are little more than a sub-culture. It takes time-zones to amplify the cultural fissioning of fan-fiction or knitting into a full-blown conspiracy. Their interests are commercial, industrial, cultural, culinary. A Tribesman will patronize a fellow Tribesman's restaurant, or give him a manufacturing contract, or hire his taxi. Not because of xenophobia, but because of homophilia: I know that my Tribesman's taxi will conduct its way through traffic in a way that I'm comfortable with, whether I'm in San Francisco, Boston, London or Calcutta. I know that the food will be palatable in a Tribal restaurant, that a book by a Tribalist will be a good read, that a gross of widgets will be manufactured to the exacting standards of my Tribe.

"Like I said, though, unless you're at ground zero, in the Tribe's native time zone, your sleep sched is just raped. You live on sleepdep and chat and secret agentry until it's second nature. You're cranky and subrational most of the time. Close your eyes on the freeway and dreams paint themselves on the back of your lids, demanding their time, almost as heavy as gravity, almost as remorseless. There's a lot of flaming and splitting and vitriol in the Tribes. They're more fractured than a potsherd. Tribal anthropologists have built up incredible histories of the fissioning of the Tribes since they were first recognized-most of 'em are online; you can look 'em up. We stab each other in the back routinely and with no more provocation than a sleepdep hallucination.

"Which is how I got here. I'm a member of the Eastern Standard Tribe. We're centered around New York, but we're ramified up and down the coast, Boston and Toronto and Philly, a bunch of Montreal Anglos and some wannabes in upstate New York, around Buffalo and Schenectady. I was doing Tribal work in London, serving the Eastern Standard Agenda, working with a couple of Tribesmen, well, one Tribesman and my girlfriend, who I thought was unaffiliated. Turns out, though, that they're both double agents. They sold out to the Pacific Daylight Tribe, lameass phonies out in LA, slick Silicon Valley bizdev sharks, pseudo hipsters in San Franscarcity. Once I threatened to expose them, they set me up, had me thrown in here."

I looked around proudly, having just completed a real fun little excursion through a topic near and dear to my heart. Mount Rushmore looked back at me, stony and bovine and uncomprehending.

"Baby," Lucy said, rolling her eyes again, "you need some new meds."

"Could be," I said. "But this is for real. Is there a comm on the ward? We can look it up together."

"Oh, that'all prove it, all right. Nothing but truth online."

"I didn't say that. There're peer-reviewed articles about the Tribes. It was a lead story on the CBC's social science site last year."

"Uh huh, sure. Right next to the sasquatch videos."

"I'm talking about the CBC, Lucy. Let's go look it up."

Lucy mimed taking an invisible comm out of her cleavage and prodding at it with an invisible stylus. She settled an invisible pair of spectacles on her nose and nodded sagely. "Oh yeah, sure, really interesting stuff."

I realized that I was arguing with a crazy person and turned to the doctor. "You must have read about the Tribes, right?"

The doctor acted as if he hadn't heard me. "That's just fascinating, Art. Thank you for sharing that. Now, here's a question I'd like you to think about, and maybe you can tell us the answer tomorrow: What are the ways that your friends-the ones you say betrayed you-used to show you how much they respected you and liked you? Think hard about this. I think you'll be surprised by the conclusions you come to."

"What's that supposed to mean?"

"Just what I said, Art. Think hard about how you and your friends interacted and you'll see that they really like you."
