Without it I am sure a lot of people I have learned a lot from on HN couldn't have told the things they have done or at least I couldn't have asked or answered a lot if questions. (I mean there is a massive difference between talking about working in such a type of company and having this kind of problem and being on permanent record as the bloke from acme corp who admitted they actually had such and such problem.)
