I’ve just been invited to “make a connection” online on a business networking site with someone who says they are an “Entrepreneur/Management/Sales”. His profile says he has 303 “friends” in a network of “69,799”. I’ve never met him. So exactly how useful is this person going to be to me? Answer: hardly at all. How could anyone so undiscerning (303 friends) over who they network with actually be worthwhile knowing?
