It’s been a pleasure to talk to marketers and agencies at AdTech San Francisco about how I see brands can best take advantage of social networks such as Twitter and Facebook and I delivered a message I think very different than what most of them do. Most brands see the world in terms of how much exposure (impressions) they are getting or how many followers and fans… It is not about doing another campaign, it is about listening, replying an building long term trust and it is much more difficult, it also takes years and does not come easily.
