It seems that social networks, what they are, what they do, does an enterprise need one, etc are the topic of the moment when I am meeting people. Possibly this is because the cloud message has been heard enough times that it has reached a stage where a CIO has either grasped what it means to them in the next year, or given up! Relatively commonly, it’s because they have social networks springing up all over their enterprise as at least some of their employees decide to make use of the capabilities. There is a last group and it’s those who have invested in good quality collaboration tools and don’t see why they are not being used, or why social networks are needed as well.
