I'm sorry to hear about your bad news too musico. I know it sucks to get a rejection, but you wana go somewhere where the profs really want you and will make the utmost effort to help you progress in your career, and I doubt people who won't respond to your attempts at contact would give you the support you need. I've been told by many profs that getting in contact is a great way to help personalize your app, so I think you definately did the right thing! However, having said that, I wouldn't worry too much about not getting in contact Soclose, plenty of people don't & it's not expected at most places. Plus the whole meeting profs in person / corresponding via email deal was pretty scary, I worried so much about creating bad impressions!!
I'm waiting on Yale and Princeton too...I'll update as soon as I hear anything. I hope everyone gets some good news soon!
