Am studying for my exam tomorrow (Which is Foucault heavy) by taking a 15 minute break from the books to prove why it's BETTER that we didn't learn who Gossip Girl was on the season finale. None of my friends agree with me on this one at the moment, but I am using Foucault here to prove why I am right.
Okay, so Gossip Girl turned out to be "everyone." This is actually clever. Think about it, it really doesn't matter WHO she is. She is interchangeable. She could be anyone who knows how to write a blog. Gossip Girl may seem like the ultimate puppet master who decides what she be revealed about whom and women, but her power comes from below. All the Constance and St. Jude's students have agency here. They are the ones who do the scandalous things about which Gossip Girl gabs, and, most importantly, they are the source of her tips. Gossip Girl can't be at all places at once, and so she relies on people to feed her Internet Gossip discourse by sending in what they know. If she didn't have countless informants, Gossip Girl would be powerless. Gossip Girl is who she is because EVERYONE empowers her. Thus, she is everyone and no one. Her blog is the perfect example of a Foucauldian web of power.
These kids have agency. Every single main character I believe has been shown sending a tip to Gossip Girl at some point on the series (except Nate, because I think he is too stupid to know how to work his sidekick). If you didn't secretly want Gossip Girl to write about you, why would you keep her site popular and maintain her powers by giving her the ability to write about other people? They are all Gossip Girl and they all want to be followed by her. Without Gossip Girl's coverage, after all, you are "irrelevant."
See, studying CAN be fun!
