The business consultant network Zintro pulled research from more than a dozen sources including Mashable, Facebook, Twitter, LinkedIn, Google and Quantcast to put together this infographic, which will help you figure out which social network is best suited to your social media strategy.
Although a lot of this information may not be new to you, I love the at-a-glance way of seeing the different ways in which social media platforms function. I also see it as a great presentation tool to introduce new clients to the wonderful world of social media.
