Let the word go forth, from this day forward: Brian Williams does not use Twitter. And he will not use Twitter until he has something “interesting enough” to say in 140 characters or less. In this, BriWi is defying, apparently, the gods of 30 Rock and their campaign get each of their on-air personalities to use the service…but, then, he’s BriWi. So he can pretty much do whatever he wants. (And, yes, that includes making fun of Jon Stewart.)
