Am I the only one not seeing the argument in the blog post? All I read was "LinkedIn is bad and being on it does more harm than good" without anything to support the premise. I've been on LinkedIn for years and it did nothing but good for me. I found nothing but quality jobs on it, I stopped visiting job websites as a result, I'm getting approached by companies as a result instead of me applying. I don't understand what the author was doing to find LinkedIn "bad" and "more harm than good". I think this is nonsense.
