As anyone who heard “Imagine” fifty times at the dentist will tell you, yesterday was the 30th anniversary of the assassination of John Lennon. The former Beatle has always been a cultural lightning rod, in part because of his intense popularity among people who do not otherwise like music, and in part because he was—in perhaps the most accessible, non-threatening use of the phrase ever—the smart one.* It was therefore satisfyingly ironic when, around 11:30 Eastern yesterday morning, “Lenon” eclipsed “Lennon” as a trending topic on Twitter. “Lenon” continued its meteoric rise throughout the day and, as of this writing, has knocked “Lennon” clean off the trending topics list. It was a watershed moment in the measurement of world stupidity. Either that or it was a startlingly apt metaphor for our national discourse, naturally synthesized by our most contemporary medium of communication—a free hint from the ghost in the machine.
