Stanford is still offering interview invites... And they're interviewing through April. If you haven't heard back from STanford thus far, consider that good news--b/c at least you're still in the game. I'm in the same crowd as you... waiting waiting waiting. I even work right next to the MSOB... Anyways, g'luck!!!!
Thanks for the encouragement; I called the admissions office out of curiosity and they informed me that they no longer inform applicants of their status over the phone and that anyone who has been waiting for an interview should hear something "very soon."
Hope that helps guys, and good luck to everyone in this random, crapshoot process!
