Wait, is something OOC simply because it's ludicrous?
I don't know about other people, but I roleplay as someone with a sense of humour. Sometimes I make jokes which are thoroughly IC, and well, they're not any less IC because they're intended to be funny. And in particular, connecting Moo with cows strikes me as an IC reference, given that in the Real World talking cows do not run political organizations. (Unless they do. Hmmm. That could explain some governments )
I haven't figured out how to apply the OOC/IC line to the contents of the main OWF yet. It seems to me that the majority of posts in OWF these days are IC-oriented; a lot of them are war propaganda posts, usually either for- or anti- Vox Populi, and in fact most of them (including the one imhotep posted recently in AP that got moved to OWF) belong in AP, as they are IC alliance drama.
