Building your network is not a traditional skill that most people are taught. However, it is a soft skill that is needed to be successful in business today. There is tremendous value in your social network beyond bragging about the number of followers that you have. (1) Start building relationships that you could potentially tap for future job opportunities, (2) Identify strategic online connects and meet them offline in the real world, and (3) Use your social networks as a visual so you know who you are looking at in person (i.e. during a conference or networking event). Social networks like Google Plus, Facebook and LinkedIn are channels that can provide direct access to decision makers while providing valuable personal and professional information about someone before you meet them.
At the end of the day the world is changing fast and each person is going to have to adapt. You can no longer depend on your employer to put you on the fast track or employ you for the next 40-years. Your future is in your hands. Handle it well.
