Thanks for taking the initiative to organize this!
The main question still open is how to handle the accommodations. There are probably more of us than the total couch capacity of NYC’s Less Wrong contingent. Sleeping bags and a large enough room/basement would probably work, though. Who’s willing to provide space, and for how many?
I think instead of worrying about finding space for people to crash, we should just distribute Modafinil to all the participants. Problem solved.
