Twitter is like proprioception
Clive Thompson, Wired magazine
It's like proprioception, your body's ability to know where your limbs are. That subliminal sense of orientation is crucial for coordination.(...)
Twitter and other constant-contact media create social proprioception. They give a group of people a sense of itself, making possible weird, fascinating feats of coordination.
So why has Twitter been so misunderstood? Because it's experiential. Scrolling through random Twitter messages can't explain the appeal. You have to do it - and, more important, do it with friends.
Here's my bet: The animating genius behind Twitter will live on in future apps. That tactile sense of your community is simply too much fun, too useful - and it makes the group more than the sum of its parts.
