It’s occurred to me recently that there seem to be basically two different types of people: the sychronous and the asynchronous. Synchronous people like to have conversations; they want to deal with things “in the present,” then move onto other things. Asynchronous folks, on the other hand, want to correspond and have some time to think things over; at the extreme, they won’t use the telephone even for simple matters due to the risk of bothering someone when they’re otherwise disposed.

Then again, maybe these are just manifestations of the broader traits of extroversion and introversion; I suspect most introverts (like me) prefer email to phone calls and IMs, while most of the extroverts I know aren’t much for email—they might read it, but good luck getting a response amounting to more than one sentence. Of course, these days you can’t really be just one or the other—although I do long for a return of the days of the handwritten letter sometimes.
