They were self-congratulatory Tweets from people who spend their days on Twitter. They were snarky encomiums directed towards the weekend assignment editors and back-up anchors on broadcasts who were clueless, maudlin, and rambly. Then, one person on the plane Tweeted a picture of the crashed jet, and suddenly, the meta-Tweets iterated. You are now participating in the real-time Twittering of a plane crash! (Hey, what's that about a Canadian plane crash, or dozens dead in Egypt? Never mind. I can listen to the San Francisco Fire Department scanner online now.)
