How Twitter Will Change the Way We Live

Evan Williams and Biz Stone of Twitter


The one thing you can say for certain about Twitter is that it makes a terrible first impression. You hear about this new service that lets you send 140-character updates to your "followers," and you think, Why does the world need this, exactly? It's not as if we were all sitting around four years ago scratching our heads and saying, "If only there were a technology that would allow me to send a message to my 50 friends, alerting them in real time about my choice of breakfast cereal."


I, too, was skeptical at first. I had met Evan Williams, Twitter's co-creator, a couple of times in the dotcom '90s when he was launching Blogger.com. Back then, what people worried about was the threat that blogging posed to our attention span, with telegraphic, two-paragraph blog posts replacing long-format articles and books. With Twitter, Williams was launching a communications platform that limited you to a couple of sentences at most. What was next? Software that let you send a single punctuation mark to describe your mood? (See the top 10 ways Twitter will change American business.)

And yet as millions of devotees have discovered, Twitter turns out to have unsuspected depth. In part this is because hearing about what your friends had for breakfast is actually more interesting than it sounds. The technology writer Clive Thompson calls this "ambient awareness": by following these quick, abbreviated status reports from members of your extended social network, you get a strangely satisfying glimpse of their daily routines. We don't think it at all moronic to start a phone call with a friend by asking how her day is going. Twitter gives you the same information without your even having to ask.

The social warmth of all those stray details shouldn't be taken lightly. But I think there is something even more profound in what has happened to Twitter over the past two years, something that says more about the culture that has embraced and expanded Twitter at such extraordinary speed. Yes, the breakfast-status updates turned out to be more interesting than we thought. But the key development with Twitter is how we've jury-rigged the system to do things that its creators never dreamed of.

In short, the most fascinating thing about Twitter is not what it's doing to us. It's what we're doing to it.

The Open Conversation
Earlier this year I attended a daylong conference in Manhattan devoted to education reform. Called Hacking Education, it was a small, private affair: 40-odd educators, entrepreneurs, scholars, philanthropists and venture capitalists, all engaged in a sprawling six-hour conversation about the future of schools. Twenty years ago, the ideas exchanged in that conversation would have been confined to the minds of the participants. Ten years ago, a transcript might have been published weeks or months later on the Web. Five years ago, a handful of participants might have blogged about their experiences after the fact. (See the top 10 celebrity Twitter feeds.)

But this event was happening in 2009, so trailing behind the real-time, real-world conversation was an equally real-time conversation on Twitter. At the outset of the conference, our hosts announced that anyone who wanted to post live commentary about the event via Twitter should include the word #hackedu in his 140 characters. In the room, a large display screen showed a running feed of tweets. Then we all started talking, and as we did, a shadow conversation unfolded on the screen: summaries of someone's argument, the occasional joke, suggested links for further reading. At one point, a brief argument flared up between two participants in the room — a tense back-and-forth that transpired silently on the screen as the rest of us conversed in friendly tones.

At first, all these tweets came from inside the room and were created exclusively by conference participants tapping away on their laptops or BlackBerrys. But within half an hour or so, word began to seep out into the Twittersphere that an interesting conversation about the future of schools was happening at #hackedu. A few tweets appeared on the screen from strangers announcing that they were following the #hackedu thread. Then others joined the conversation, adding their observations or proposing topics for further exploration. A few experts grumbled publicly about how they hadn't been invited to the conference. Back in the room, we pulled interesting ideas and questions from the screen and integrated them into our face-to-face conversation.

When the conference wrapped up at the end of the day, there was a public record of hundreds of tweets documenting the conversation. And the conversation continued — if you search Twitter for #hackedu, you'll find dozens of new comments posted over the past few weeks, even though the conference happened in early March.

Injecting Twitter into that conversation fundamentally changed the rules of engagement. It added a second layer of discussion and brought a wider audience into what would have been a private exchange. And it gave the event an afterlife on the Web. Yes, it was built entirely out of 140-character messages, but the sum total of those tweets added up to something truly substantive, like a suspension bridge made of pebbles.
