The New York Times has a good article on the impact that Facebook and Twitter are having on culture today.
Social scientists have a name for this sort of incessant online contact. They call it â€œambient awareness.â€ It is, they say, very much like being physically near someone and picking up on his mood through the little things he does â€” body language, sighs, stray comments â€” out of the corner of your eye. Facebook is no longer alone in offering this sort of interaction online. In the last year, there has been a boom in tools for â€œmicrobloggingâ€: posting frequent tiny updates on what youâ€™re doing. The phenomenon is quite different from what we normally think of as blogging, because a blog post is usually a written piece, sometimes quite long: a statement of opinion, a story, an analysis. But these new updates are something different. Theyâ€™re far shorter, far more frequent and less carefully considered. One of the most popular new tools is Twitter, a Web site and messaging service that allows its two-million-plus users to broadcast to their friends haiku-length updates â€” limited to 140 characters, as brief as a mobile-phone text message â€” on what theyâ€™re doing. There are other services for reporting where youâ€™re traveling (Dopplr) or for quickly tossing online a stream of the pictures, videos or Web sites youâ€™re looking at (Tumblr). And there are even tools that give your location. When the new iPhone, with built-in tracking, was introduced in July, one million people began using Loopt, a piece of software that automatically tells all your friends exactly where you are.
So how does all of this fit together?
This is the paradox of ambient awareness. Each little update â€” each individual bit of social information â€” is insignificant on its own, even supremely mundane. But taken together, over time, the little snippets coalesce into a surprisingly sophisticated portrait of your friendsâ€™ and family membersâ€™ 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 â€œa type of E.S.P.,â€ as Haley described it to me, an invisible dimension floating over everyday life.
