I decided that, if I were to write a teen series, I'd want to set it in a place that was familiar to me - Manhattan, where I'd grown up - and I'd model the characters on myself and my friends.

I certainly didn't say while writing 'Gossip Girl,' 'Oh this is going to be big!' It was really like, 'Oh god, everyone's gong to hate these people! They're so bratty!' But I actually think what is so appealing about them is the humor in them.
