Then feel free to wonder why an intelligent young woman feigns astonishment when her candid shot creates a hubbub online after she disseminated the shot to 76,000 followers. Isn’t that the point of posting on Twitter? Highlighting everything? Even your socio-political thoughts on cup sizes?

Twitter’s popularity and usefulness are a mystery to me. Pressed by personal, professional and cultural forces, I sporadically deploy short missives for fear of becoming one of those cantankerous technophobes who is too dense to recognize the miracle of letting “followers” know I hate raisins or that I loved the finale of “Mad Men.”

Now, not only am I expected to transmit this minutiae mere seconds after I think it, some 20-year-old in California has decreed that I must do it within the brevity of 140 characters. This need for conciseness, in fact, induces normally articulate friends of mine to write in Prince lyrics — recklessly using “2” and “4” and “U” as words.
