I'm a pretty big nerd, especially by your standards. I watch a lot of cartoons and anime, and talk about them on the internet (I only have one friend IRL who are into stuff like that as I am). I play a lot of video games, none of them "casual". I watch more hentai than I do normal porn (hooray 4chan). I can spend hours reading wikipedia articles, just learning for the sake of learning. My favorite subject is science, specifically astro, particle and quantum physics, and some of the weirder and more dangerous parts of chemistry. Recently, I've been into genetics, and a few other areas of biology, mostly viruses and single cell organisms.
Also, since we're posting code, first thing I found on my computer is this simple RNG I made a few years ago for a programming class:
I don't know a lot of python. I know HTML, CSS, and am learning other web languages, such as PHP and SQL.
I'm a Comp Sci major, though I might change to Info Tech or Physics. Although, I want to eventually become a game designer, and Comp Sci would probably be the best for that.
I've never seen why people don't like the word, or act like being a nerd is a bad thing.
