No WL for me today, but I'm guessing I'll hear in the next round of dings, since I didn't get around to sending a LOCI.
I don't think Harvard cares much about LOCIs. They know that, except for the 200-odd people who get into Yale, pretty much everyone who gets into Harvard will go.
I think it's worth pointing out that all of yesterday's waitlists went to people who submitted before Winter Break. I'm not sure if that means the post-Winter Break holds are still in contention for JR1s and JR2s, or if it just means that we're headed for the waitlist later on, but it's worth noting.
At least it gives them time to read my new LOR.
