A Network First? Katie Couric Tweets Her ‘Goodnight’

Tonight at the end of CBS Evening News, @katiecouric tweeted her goodnight. And at the quick pace she typed, she’s either really good on her Blackberry, or she had it pre-written and just hit ‘send.’ Either way, for Twitter to be introduced in such a personal way on a program watched by about 5 million people — an audience not known to be frequented by social media savants — this is somewhat of a first.
