How important, with MeFi or Meta posts and comments, are extraneous factors like time, caffeine, midwork intervals or alcohol? Is there really a before and after coffee; a morning and late night inflection; according to how long you've been up and what you've ingested to get through the day? I think there is. Is the time-stamp your best counsellor and friend? Specially considering the wildly disparate time-zones? No names mentioned; just saying. In my humble opinion, the hour (and the perceived condition or, more generally, circumstances) says as much as the name. If not more.
