Ephems AFK* for three weeks

Ephems is about to go on holiday for the next three weeks and will be virtually without internet access, so unable to reply to comments on its own posts for some time, however penetrating, informative, inaccurate, misleading, ignorant or bigoted those comments might be.  So for three weeks you can get away with almost anything.  Floreat spamma!   But don't worry:  I'll be back…

*For any of the uninitiated who might accidentally stray onto this page, AFK = Away From Keyboard.  But you knew that really.
