I'll admit it, I was a bit slow to "get" social media. Intellectually, I understood the viral and interconnected nature of the media. But I was schooled in mainstream media. When I started in radio we still spun records and spliced tape with a razor blade. I read the articles and heard the mantra: it's not simply the number of your followers that count on Twitter, but who is following you, and how much influence they have. This lesson hit home for me during a recent trip to San Francisco.
