A few years ago I may have begged to differ. However after starting up my own social networking presence I have to say that this is a critical component to opening career doors (at least the good ones). The serious professional really needs to be up and running on the major social networking channels to stay current. Even when you are not looking for a job, you are developing your skill sets. This is because there is so much idea sharing that occurs if these sites are harnessed to their fullest potential. I’ve gotten hooked and love the world of networking.
