Haha, good analogy. However, traffic rules are rules, not guidelines. To my knowledge, there aren't any "rules" for status upating, or are there?
There isn't, it's such a harmless feature that I doubt they care much about creating any rules for it and to just follow the general forum rules.
And the trading post is there for a reason. You don't drive on the wrong side of the road during rush hour and say "hey no one is using the outbound lane anway."
Last time I checked, nothing really serious was going on in the status updates, if anything should be brought up and gained attention, then the person should be making a topic for it to allow more transferring of information, if it's something silly, we again, have the Chit-Chat threads for a reason, nobody should be having a serious discussion in a Facebook-esque status in the first place, there's a stupid character limit and the status is just going to be blown out of the recent area sooner or later anyways.
