I don’t care if you never before heard of my guest, social media guru Sarah Szalavitz. A week ago, frankly, neither had I. But I suspect that at the end of this hour, we’ll all want to hear more from Sarah. Or maybe we’ll just want to be her. Sarah is the co-founder of 7 Robot, a new company involved in digital storytelling and social design. (Some examples: ZapRoot, .) More about that, later, because that’s just her latest career. A Harvard-trained lawyer, that credential is almost incidental in a resume that includes two years as assistant to then-Speaker of the California State Assembly, Willie Brown Jr. More recently, she was director of content development for Veoh Networks.
