I have never heard of Professional Networking Strategies nor am I totally convinced it is necessary. I understand the purpose of LinkedIn and it seems convenient especially when the future employer looks for writing examples. However, I do not think it is necessary. There is nothing wrong with a paper copy, but I was also raised in the country where life is simple and people around here like to stay away from the computers because they do not trust them and they cause more trouble than good. Also my current employer has a folder with my name on it and everything I have every completed or had to turn in for the State. Including my resume.
