It's not my little ruleset and I agree that a writer doesn't have to hang out with other writers to get work done, or work in blocks of exactly 10 to 50 minutes; I just think you were very vague and never gave a specific objection to the content of the rules, which is quite a spineless thing to do. Prof. Robert Boice may be wrong, but at least his positions are stated clearly enough that we can see they're wrong.
