When Gossip Girl, the show, began Gossip Girl, the person, was one of the most talked about characters in real life, and in the show. But nowadays I feel she's being sidelined!
Obviously, her character is a person who has some issues (which made her make a gossip blog about the manhattan elite) and probably knows the show's characters at some level.

But I can't help but wonder who she would be if the writers ever decide to write a real character for her. It would be fun to see how she works and what everyone's reaction is when her cover is blown and how she herself reacts to this.
