Not enough thought, in my view, is going into facebook as a brand/business platform. Nor is it being taken seriously enough by brand teams. Millions of people use Facebook, but still brand activity tends to focus on ads or search engine optimisation, rather than on engaging in a strategic way with these new platforms which people are spending most of their time on.
