If I've stalked your profile, there's a good chance that it's because something in it has been flagged. I'm addicted to flagmod, and I can't help but look at the occasional profile. Either that or I'm just randomly going through profiles, looking for interesting people and inappropriate images.
I like: A certain degree of geekiness. Intelligence; the more, the better. Moderate cynicism. Alabaster skin. Charles Tyrwhitt catalogs. Proper grammar and spelling. Conversations about everything and nothing that go on for days. Maturity. Childishness. Interesting quotes. Dynamic memory allocation. Athletic girls. Musical ability. Horn-rimmed glasses. Penny Arcade.
I intensely dislike: Fear. Stupidity (especially my own, which my field reminds me of constantly). "I can't describe myself/I can't summarize myself in a little box" profiles. Tone deaf buskers. Total snobs. Closed minds. Decaffeinated coffee. People who believe that I'm nice despite all evidence to the contrary. The substitution of single letters for whole words.
I love things that are beautifully simple. Then again, I also love things that are incredibly ornate. I really enjoy the interplay of ideas with reality; both computer science and law involve the use of words to change behaviour, which is alarmingly close to magic.
