Anyway you look at it, Social Media Marketing has become pervasive in our personal and professional lives.
One of the way to engage your social network is to "push" quality content to the top tier social networks (Digg, Facebook, Twitter etc.) Another way is to uses well designed widgets to "pull" like your minded audience to your website and blogs. Here's an example of such a social media widget.
