<p>The best thing about twitter is the name. We’re like flocks of birds tweeting at each other. Most of it, as the name implies, is just chirping. Some of it carries meaning: here I am! watch out for the cat! here’s some food! </p>
<p>It has had some effects that are, to me, uncannily like flocks of birds. A sports reporter tweets about a trade. Other reporters immediately tweet that. Talk radio jumps on this. People start calling. They tweet others. Then it turns out the first tweet was a fake. Or was wrong. The noise subsides. The flock is quiet. </p>
<p>In this sense, twitter reminds me of an essential human quality: making noise, sometimes for no particular purpose other than because we make noise. Can’t fight what we are.</p>
<p>Another aspect is that tweets are glimpses. A glimpse of leg. Saw a celebrity. Big backup at the Allston tolls. Why are glimpses meaningful? Because the mind fills in a picture. A favorite example is the story in Citizen Kane when Bernstein describes seeing a woman in a white dress. She never turns around so he can continue to imagine her as she might have been. Our minds require image making. Tweets are little jolts, like sips of coffee. Which explains in part why some people find it addictive: their minds build these little stories and they become caught up in the flow of little jolts, looking for something, chasing something. To use another cultural reference, it’s the green light at the end of Daisy’s dock, always flashing, always reminding us that it’s right there but just out of reach.</p>
<p>Connected to glimpses is anticipation. There’s the sense that something might happen. I relate this to TV and research on how we experience TV. (Surprisingly little good research on this, to my mind.) In sum, TV is a low investment, low payback experience. Costs nothing to sit, change channels, wait for something to give you even a little bit back. A hobby or sport or other activity requires a higher investment of energy. Gives you much higher payback, which is why staying away from TV for a week doesn’t work but a month does: a week isn’t long enough for you to become used to the expense required to get the higher payback. Step away from a low return activity for long enough and it bores you. You need more. Twitter is like that: step away from it for a while and you wonder why you enjoyed it at all. Get involved in it and you find yourself looking, looking, checking, checking for a bit that interests you. Low investment required to check, low reward in return. (Apply this to the way nearly everyone looks at their phones now. Low return, low investment. Lift your head, ignore the phone for long enough and you think, “Wow, that’s so boring.” But like Michael Corleone, it sucks you back in.)</p>
