Last month I caught up with Elisa Camahort when we were in DC. Although I've been involved, as a speaker, editor and supporter, of BlogHer since the early days (It's strange to think that less than 2 years can be called "the early days" in social media.) I was curious to learn how within, what seemed like seconds, BlogHer had morphed from one workshop - to an online community - to an ad network - to two niched conferences.
