"An early clue to the new direction?"

When I came across this London Times piece about the serious attention being paid by fund managers, CEOs and analysts to How Teenagers Consume Media, an anecdotal report by a precocious 15-year-old, I couldn't help thinking of the priceless scene in A Hard Day's Night where George Harrison's sardonic witticisms badly rattle a trend-conscious TV producer. On the other hand, maybe the kid's right: After all, if a geezer like myself is Twittering, perhaps we've already reached the point where such activity is "strictly for the elderly." Ouch.
