"Interesting" is a pretty difficult trait to compare people with. I don't think I'd be able to single out anyone. Often the people who are weirdest aren't that interesting to me because they're a little too eccentric which often means you know what you're going to get every time - eccentricism. I prefer people who I get along with and find them interesting purely because of that. With that in mind, I would say that Danielle, Dan, Jess, Lev, Nicky, Sarah and so forth (this is where I realised the list will go on for a while!) are probably the most interesting.
