, funny enough, I had a conversation about that last night. Not simply why it exists but also why it's so successful. (We know it's successful because not only did they bring it back but they also made it longer.) They are resurrecting the water cooler conversations of yesteryear. In the internet age, we've lost the common space to engage in discussions about shows - instead simply shouting about our excitement and thoughts in the form of non-conversational tweets and status updates. The show simulates, but does not fully replicate, getting some people together to actually have a conversation about a show they enjoy. It's pretty awesome that way.
