Slate has started running a hilarious, erudite travelogue cum (and I mean cum) history of sex clubs, sex societies, sex orders, treehouses, fraternities, and assorted other carnal associations in 18th-century England.  Written by the historian Tony Perrottet, each installment takes 5 minutes to read–10 if you are sluggish like me–but will lighten all 24 hours of your day.  And your keyboard will remain dry.
