I'll leave discussion about valid of KM's activity aside, what is it about the "I know X, genuinely great people and really want to do good stuff" formula (with no substantive arguments) that seems to make to the top of these hn debates? (I'm sure the KM people love puppy dogs, etc).
Indeed, it's annoying. I'm sure most spammers, phishers etc love their mom and are cool guys when you meet them over coffee or drinks. It says nothing about their business ethics.
