I'm also a bit of a geek and love to learn about pretty much everything, but particularly history and science. I can spends hours at a time reading Wikipedia, filling my brain with random trivia.
Personality wise, I'm a very honest and open person, possibly because I'm such a poor liar ;). Seriously though, I think being honest upfront and dealing with the consequences immediately, turns out better in the long run as the truth usually comes out. I also prefer people to be honest with me about my flaws, so I know what I need to work on in the future.
I value quality of my friendships over quality. It takes me a while to warm up to people, but I find that the people I become friends with, I stay close to in the long run. I still keep in touch with two friends from kindergarten, and last year eight friends from high school flew out to visit me, at the same time! As you can imagine, it was quite the party.
