In an era in which every “event” has at least three sponsors and multiple guest lists to confuse clipboard girls, blogger Choire Sicha’s taking a simpler approach for his upcoming HarperCollins book. “Please join me for a party for ‘Very Recent History,’ ” his invite reads. “No speeches, no toasts, no liquor sponsors . . . and no dumb book party garbage whatsoever.” The venue Aug. 6 will be the unsubtly named East Village club the Cock, where Sicha warns, “watch your wallets and . . . sex is expressly forbidden on the premises.”
