Rules? Guidelines?

Larry Sanger (Citizendum) posted this today. UGH. Guidelines and policies.  If you know me, you know I love rules and I stick to them, pretty much all of the time.  However, with Web2.0 and user-generated content it is a much fuzzier view.  I am in a toss up about this.  On one hand I am all for free speech, etc. and on the other – we need to have structure.  Say what you want, but there needs to be structure.  Basically, as our mothers would have said “there is a time and a place for everything”.  Outside of structure, this begs the question of credibility.  This is such a large, abstract argument.  If you can, read Larry’s post and give it some thought.
