I believe most of us know all the mayor social media playforms. We also know which services/functionalities they offer and how that might contribute to our organizations. But when we look at branding, exposure and leadgeneration we wonder how effective the chosen platform is.
My American colleague at TiasNimbas showed me a great articel on CMO and Posterous. It showes which platform can be best used for communication, branding and lead generation. It was very usefull for my social media strategy.
