Take a look at an infographic just released by Online MBA titled "A Case Study in Social Media Demographics." It gives demographic data for Facebook, Twitter, Google+, Pinterest, Linkedin, Reddit and Digg which could be useful when planning your social campaigns. The infographic also has data on how many people are using their mobile phones to do social, driving home the point of my article last week about the importance of Responsive Design for your website.
