You’re not alone; according to a Pew Research Center report on U.S. news consumption habits, 84% of Americans don’t tweet.

And I suspect they’re perfectly happy in not doing so, and in some cases, happier about it than people who do—it’s my impression that people who tweet often do so out of a sense of obligation or not wanting to feel left behind, as opposed to getting something out of it or just enjoying it.

Not that this will affect all the people who can’t wait to buy Twitter stock….

The report does say that half of Twitter users are very young, between 18 and 29, and that they tend to be more educated than the general public. But I wonder: As those users get older, will Twitter become an ingrained habit in their lives, a permanent one? Or will they just get busier and gradually disengage as the novelty wears off, the way many people seem to do with Facebook?
