If you don’t “get” Facebook and Twitter, read this NY Times article September 8, 2008

The NY Times is often considered the US newspaper of record, and it lives up to its reputation with an excellent article in today’s Sunday NY Times Magazine about the ambient awareness enabled by Facebook status updates, Twitter and other microblogging tools.

Even readers familiar with both popular microblogging tools and their history should read this article. High points:

Microblogging enables ambient awareness of your broad friendship group:

In essence, Facebook users didn’t think they wanted constant, up-to-the-minute updates on what other people are doing. Yet when they experienced this sort of omnipresent knowledge, they found it intriguing and addictive. Why?

Social scientists have a name for this sort of incessant online contact. They call it “ambient awareness.” It is, they say, very much like being physically near someone and picking up on his mood through the little things he does — body language, sighs, stray comments — out of the corner of your eye.

Ambient awareness comes not from any single tweet or status update, but from the aggregation of the data.

Haley discovered that he was beginning to sense the rhythms of his friends’ lives in a way he never had before. When one friend got sick with a virulent fever, he could tell by her Twitter updates when she was getting worse and the instant she finally turned the corner. He could see when friends were heading into hellish days at work or when they’d scored a big success. Even the daily catalog of sandwiches became oddly mesmerizing, a sort of metronomic click that he grew accustomed to seeing pop up in the middle of each day.

This is the paradox of ambient awareness. Each little update — each individual bit of social information — is insignificant on its own, even supremely mundane. But taken together, over time, the little snippets coalesce into a surprisingly sophisticated portrait of your friends’ and family members’ lives, like thousands of dots making a pointillist painting. This was never before possible, because in the real world, no friend would bother to call you up and detail the sandwiches she was eating. The ambient information becomes like “a type of E.S.P.,” as Haley described it to me, an invisible dimension floating over everyday life.

“It’s like I can distantly read everyone’s mind,” Haley went on to say. “I love that. I feel like I’m getting to something raw about my friends. It’s like I’ve got this heads-up display for them.” … And when they do socialize face to face, it feels oddly as if they’ve never actually been apart. They don’t need to ask, “So, what have you been up to?” because they already know. Instead, they’ll begin discussing something that one of the friends Twittered that afternoon, as if picking up a conversation in the middle.

“It’s an aggregate phenomenon,” Marc Davis, a chief scientist at Yahoo and former professor of information science at the University of California at Berkeley, told me. “No message is the single-most-important message. It’s sort of like when you’re sitting with someone and you look over and they smile at you. You’re sitting here reading the paper, and you’re doing your side-by-side thing, and you just sort of let people know you’re aware of them.” Yet it is also why it can be extremely hard to understand the phenomenon until you’ve experienced it. Merely looking at a stranger’s Twitter or Facebook feed isn’t interesting, because it seems like blather. Follow it for a day, though, and it begins to feel like a short story; follow it for a month, and it’s a novel.

Ambient awareness helps maintain “weak ties”. Sociological research has shown that a large network of weak ties is more likely to be helpful than a small network of strong ties when trying to do things like get a job, find a mate, and other socially tinged objectives

Many maintained that their circle of true intimates, their very close friends and family, had not become bigger. Constant online contact had made those ties immeasurably richer, but it hadn’t actually increased the number of them; deep relationships are still predicated on face time, and there are only so many hours in the day for that.

But where their sociality had truly exploded was in their “weak ties” — loose acquaintances, people they knew less well. It might be someone they met at a conference, or someone from high school who recently “friended” them on Facebook, or somebody from last year’s holiday party. In their pre-Internet lives, these sorts of acquaintances would have quickly faded from their attention. But when one of these far-flung people suddenly posts a personal note to your feed, it is essentially a reminder that they exist.

Microblogging, ambient awareness and maintaining weak ties has the sideeffect of making it impossible to move away and “reinvent yourself” as your past will always be with you.

This is the ultimate effect of the new awareness: It brings back the dynamics of small-town life, where everybody knows your business…

“It’s just like living in a village, where it’s actually hard to lie because everybody knows the truth already,” Tufekci said. “The current generation is never unconnected. They’re never losing touch with their friends. So we’re going back to a more normal place, historically. If you look at human history, the idea that you would drift through life, going from new relation to new relation, that’s very new. It’s just the 20th century.”…

“If anything, it’s identity-constraining now,” Tufekci told me. “You can’t play with your identity if your audience is always checking up on you. I had a student who posted that she was downloading some Pearl Jam, and someone wrote on her wall, ‘Oh, right, ha-ha — I know you, and you’re not into that.’ ” She laughed. “You know that old cartoon? ‘On the Internet, nobody knows you’re a dog’? On the Internet today, everybody knows you’re a dog! If you don’t want people to know you’re a dog, you’d better stay away from a keyboard.”
