This window is now closed. You can read the Compleat Reddit Dialogue now without fretting you'll miss anything. You can read the TNR pre-publication book excerpt that the Reddit AMA ("Ask Me Anything") was at least ostensibly about here. You can read a second pre-publication excerpt that ran in the Atlantic Online here.
You can pre-order the book itself here.
You can read my annotations to the long-forgotten topical references in Cole Porter's "You're The Top" (which I actually allude to in the AMA after discussing my rock-star nephew's income) here. Followup on "Drumstick Lipstick" (which stumped me on the first go-round) here. Second follow-up about the smutty parody version attributed, implausibly, to Irving Berlin, here.
