Youbiquity allows you to share both your current location as well as your future travel destinations with your HBS classmates. An HBS email account is needed to sign up, and everything is done at a city level, so you can rest assured that your privacy is safe. Through Youbiquity, you can find out who's hanging out in the city you find yourself in, and also figure out whether anyone has travel plans for the same destinations as you and whether those dates overlap. No more "Is anyone going to be in NY this weekend?" messages!
