Texting has reached the point where we expect people to see and respond to their messages immediately. Email, too, at least during business hours. The only "non-urgent" form of electronic communication I can think of now is Facebook messages. We don't expect people to be on Facebook constantly, so any messages we send there can be ignored for a while, but that means sending all of our non-urgent personal communications through Mark Zuckerberg. I don't like that idea.

PS - And when you think of it, we probably shouldn't send anything that way.
PPS - But who's going to do stop?
