I love to know how things work, from big things, like how the universe works, to something simple as why clocks tick. Wikipedia, tvtropes and other information repositories tend to be like crack to me. I've often ended up going to bed at 8am thanks to getting lost trying to absorb every piece of information I can find.
I have a strong computers and technology bent, you'll find that my apartment is full of various gadgets and computers often in various stages of being dismantled. I've been into technology since a young age, my parents encouraged my tinkering despite the large number of household appliances which never ended up quite working properly after I'd gotten hold of them.
