As far as digital is concerned, this is Marissa Mayer's week, but let the Social Media Insider get your mind off that. For a few minutes, let's not worry about whether a pregnant Silicon Valley superhero can really run a struggling Internet concern, and worry just a little bit, about Mark Zuckerberg and Sheryl Sandberg, not to mention thousands of down-in-the-dumps Facebook shareholders. Yes, let's talk (again) about Facebook. A week from now, Facebook will announce its first earnings as a public company, and the Social Media Insider, along with all those bitter Facebook haters, will be out in force. Given the context of these post-IPO months, these earnings will read like the Rosetta Stone of social media, whether that's fair or not, so get ready.
