This is a super interesting topic, does anyone know, why it disappeared from the front page? (also didn't find it in any of the following pages) I don't see it flagged, it has quite a lot of points and comments, what happened? Also read a super interesting comment here in this thread (the comment is also gone by now): it said that people write technical books/lengthy articles with the objective to win contracting work, by counting as an expert. Can anyone expand on that, and how to win friends and influence in this manner?
