So, anything military/ tech/ political/ etc. related he says that goes somewhat beyond common knowledge is not allowed to be discussed?
I think it means more like not derailing it or nitpicking about minor stuff like I don't know if you've ever been to /k/ or TFR or the Something Awful forums but people
will make a fight on some stupid mistakes in terms of terminology either seriously or ~*ironically*~ or to boast on their niche knowledge about something and the intention of the rule is to prevent threads from derailing into shitballs that have nothing to do with the original context of the thread.
But I agree that I don't think it's the best idea for a forum, any forum, to try to make minor adjustments to the forum culture by adjusting the global rules, especially when people who'd most likely be breaking these rules would make them anyway, regardless of what it says on the dotted line. Like Holdek said, the forum ratings are a good way for the community to communicate to the staff what posts are deemed bad and while this forum isn't a democracy,conversation cultures are largely formed organically by the people posting in them, rather than being warded off by rule. Clarifications to existing rules are still extremely welcome and yeah, the forum rules need updating every once in a while, but trying to micromanage posting from the macro level is exceedingly inefficient.
It's hard to say like, "no jokes", but when I read discussion it often makes me grimace because it's usually so awkward and force. It's rarely directly contributive.
I was never into "Meemaw wants her q-sands!" either, but if a no-joke rule had been in effect, would it have warded away those posters or prevented the people who had something the majority of people would've found really funny from posting ? Would it have warded off either? The staff ultimately makes the decision what kind of discussion they want but it might be easier to let the staff give bad posters anymous dunce caps instead of trying to appeal to would-be-bad-posters via the forum rules in the off-chance they read them.
That all being said, I think the new rules seem nice and clear enough, the only thing I'd change really imo, is the "Be legal" being it's own point in the rules in Lolcow discussion, because it could easily be included in "1. Be civil.".
