Really, could New York Times executive editor Bill Keller be any more ham-handed? And would he, in his right mind, actually sign off on his own Times Magazine columns?

Latest case in point: Keller’s piece for this Sunday’s magazine about the noodlenik nature of social media:

My mistrust of social media is intensified by the ephemeral nature of these communications. They are the epitome of in-one-ear-and-out-the-other, which was my mother’s trope for a failure to connect.

I’m not even sure these new instruments are genuinely “social.” There is something decidedly faux about the camaraderie of Facebook, something illusory about the connectedness of Twitter. Eavesdrop on a conversation as it surges through the digital crowd, and more often than not it is reductive and redundant. Following an argument among the Twits is like listening to preschoolers quarreling: You did! Did not! Did too! Did not!

As a kind of masochistic experiment, the other day I tweeted “#TwitterMakesYouStupid. Discuss.” It produced a few flashes of wit (“Give a little credit to our public schools!”); a couple of earnestly obvious points (“Depends who you follow”); some understandable speculation that my account had been hacked by a troll; a message from my wife (“I don’t know if Twitter makes you stupid, but it’s making you late for dinner. Come home!”); and an awful lot of nyah-nyah-nyah (“Um, wrong.” “Nuh-uh!!”). Almost everyone who had anything profound to say in response to my little provocation chose to say it outside Twitter. In an actual discussion, the marshaling of information is cumulative, complication is acknowledged, sometimes persuasion occurs. In a Twitter discussion, opinions and our tolerance for others’ opinions are stunted. Whether or not Twitter makes you stupid, it certainly makes some smart people sound stupid.

And made Keller look stupid, as this Poynter.org piece reported:

Times Executive Editor Bill Keller explains in a new column what was behind his #TwitterMakesYouStupid tweet, which could be responsible for a massive drop in journalists’ productivity last week as they tweeted their retorts.

Bill Keller.
