I think EOS is great and that every startup should use it, but have a feeling that most HN readers will detest it because of Not Invented Here syndrome. It’s too tempting to think “How hard can it be to figure out how to run a meeting, set goals, etc.?” And then end up spending the time that should’ve been spent having meetings and working towards goals on all the minutiae and cruft that somebody else has worked out in the past.
