I haven't been accepted anywhere yet, but I posted my first (and only, so far) interview invitation (Wharton) - more than 50 "likes" so far. I have supportive friends, and have been out of school for a while, so they're all excited for me. Plus, I'm excited for me - it's tough keeping it in. I follow and am followed by some professors in programs I'm applying to on Google+ and twitter, so I'm not blasting it there. I was following them prior to deciding where to apply, but any I've found since then I'm bookmarking to follow later (it just seems weird to me to do otherwise).
