I reckon we could 'stage' a few public conflicts between staff, leading to some kind of big bust-up.
For example, Shlup closes a thread in Feedback, saying "we discussed this in Staff and we're not going to do it", then I re-open the thread saying, "like hell we discussed it! Stop making our decisions for all of us" or something similar. Or a staffer posts a thread that's borderline spam and then another staffer closes it, saying "I expected better from you!"

That kind of low-level sniping against each other would make our descent into division quite believeable for the members. We could be divided on "policy" lines: those who favour the quick, simple approach of "follow the rules to the letter because it's convenient" and the ones who want a "case-by-case, let's-be-flexible" approach.
Or something similar. I just think it'd be fun to pretend to argue for a few days before going really stroppy and declaring war on one another.
