Yes, I think there is something to be said for networking. My professors are all well-connected, but I myself am not. I think I am going to hedge my bets and contact the departments (politely of course!) to see if I can determine what aspects of my applications were weak. I'm waiting to hear back from one more school, but I'm not optimistic about it. I would definitely appreciate some feedback in case I decide to reapply in the future.
As for my interests, I've only earned a B.A. so they're still coming into focus. In general, though, I'm predominately interested in media stardom and fandom (especially their evolution in the age of new media) and all things television. Judging by my performance in this application cycle, though, I may need to reconsider!
