There's no hard and fast rule on WHERE a discussion on WikiPolicy has to be carried on. Indeed, it would hardly make sense to IGNORE discussion in one realm of the WikiKingdom simply because one felt the discussion really ought to be in another realm. (Not naming any names, or is that another one of those Roman pro- lipstick rhetorical tricks?)
Zoe, Jtdirl and some others have weighed in on the issue -- on various talk pages, as well as here on the mailing list -- and it wouldn't be surprising if any of them felt irked at having been ignored.
<slang style=surfer> Dude! Like the whole reason we have this splendid mailing list thing is, like, so we don't go surfing alone! There's, like, hazards out there: shoals, sharks, and sharp rocks, so we all gotta stick together, man! </slang>
