Until about 10 minutes ago I thought the only discernible difference between Facebook and LinkedIn was that one lacked pictures of girls in bikinis. Apparently there’s more to it than that. Mashable posted a pretty cool infographic that explains on a deeper level the difference between our favorite social media websites. It is not LinkedIn’s purpose to provide those wonderful “Day at the beach <33” photo albums that very much justify Facebook’s existence. This infographic explains how to best use LinkedIn, Twitter, Google + and Lord Zuckerberg’s Good Book to their fullest potential. Don’t waste time venting about your lost love on LinkedIn. No one cares. That’s what you’ve got Facebook for.
