According to Wikipedia, there are more than 200 notable social networks in the world. And when they say notable, they mean it. A notable social network has more than one million users and is growing at an extremely fast rate over the past 6 to 12 months. For authors in the technology world (like us), it is an absolute pain to keep up with all the changes in technology from social networking to mobile phones. We can only imagine what it is like for the normal (non-nerd) individual to keep up to date.

When we first wrote this book in 2010, we wanted to give you a brief overview of the main social networks of the time like LinkedIn, Facebook, and Twitter. They are still extremely important, however, we have witnessed an uptick in smaller sites that could also build your personal brand. It is literally every day when a new social networking site explodes onto the scene. And many of them tend to promise untold amounts of fortune pertaining to content and personal branding development. There are some sites that are valuable and others you would be better off ignoring.
