Update – September 2009: John Swainson has announced his retirement from CA. I wonder if he’ll pick up twitter next year.
John Swainson, CEO of CA, says he uses Facebook and LinkedIn but communicates mostly by E-mail (much of it on his BlackBerry) and IM and hasn’t felt compelled to jump into Twitter. “I don’t need to publish my position daily or hourly or minutely,” Swainson said in an interview, “though I’m sure my staff would consider ways for me to.”
I originally posted this quote to highlight what I saw as a growing first impression of Twitter.
