I’m so confused. The D staffers continue to build our personal brands in the new social medium (follow me! @EricCeleste), even though Wick says every tweet costs him 2 cents in wasted salary. That’s because social media sites like Twitter are huge, and getting bigger, right? You can’t write about the new-media world without experiencing it, right? But now that Oprah has stopped tweeting … I dunno. Maybe Wick’s right. I’ll ask my tweeps what they think.
