Funny you should ask...
I'm wait-listed. Congrats to everyone who got accepted! I learned from the DGS that whether they can take people off the wait list depends as much on *when* they hear accepted students are going elsewhere as on *how many* say no; apparently if other departments are oversubscribed by the time they get a "no" back, the university forces them to just give up those spots.
So if, by any chance, you happen to have a school that's a strictly better fit than Harvard, know that there's at least one person out there who'd get a lot out of you letting them know that sooner than later ??
