I am fascinated with cooking, astronomy and technology. I make jams and jellies, garden (mostly hot peppers and pickling cucumbers), pickle and BBQ. Burning hardwood is the greatest smell in the world, especially if it is giving its smoky goodness to brisket.
I have been to DragonCon every year for the last 21 years, so, yeah, there is that.
Math, science, educational pursuits.
I am not huge into movies. I like them, but rarely find 2-3 hours to take one in.
I read satire a lot, mostly political satire, as well as the occasional sci-fi/fantasy. Max Barry is one of my favorite authors, as is Kurt Vonnegut. I read dystopian literature, too: 1984, We, Brave New World, Fahrenheit 451, that sort of thing.
I watch comedies on TV, for I like to laugh . . . a lot.
I listen to classic rock, mostly, but love industrial and punk, as well. Pink Floyd is my all-time favorite, but I think Zeppelin is the greatest ever. Listen to Skinny Puppy, NiN, KMFDM,etc. Ramones, Stooges, Op Ivy, Bad Religion, etc.
Polyamory does not freak you out.
You know a great joke.
