I'm an optimist, but in the sense that I think things are pretty awful right now, but people are basically decent, and they're going to get better in the long run. And hey, things are significantly less terrible than they used to be. I'm a big fan of science, although I don't have the math aptitude to understand a the math-ier bits. Late nights and Wikipedia have filled my head with far, far too much useless trivia. Including things I really wish I could get out of my head, like the horrifying truth about ducks. Ducks, it turns out, are secretly the worst.
I have a cat, Zeke, who is objectively the best cat. They did studies, and they found he was the best cat by statistically significant margins.
...also I worked for two years as a video editor for this awful, awful alternative medicine/medical conspiracy theory place and have a visceral reaction to pseudoscience. So stuff like, say, homeopathy, makes me... snippy. And argumentative.
