General rule of thumb, if it's nerdy/eclectic/well-crafted or
weird, I'll probably dig it. I also have a weak spot for pulp and
generally terrible things.
Since that's probably as clear as mud, here's some examples:
Books (made-up shit): Jorge Borges, Neal Stephenson, China
Mieville, Tom Robbins, Ursula Le Guin, Iain Banks, Linda Nagata,
well written Lovecraftian fiction, old school sci-fi of the
Niven/Clarke/C.L. Moore/Stapledon school. Also, I can chew on most
good pulp fiction and I have a weakness for retarded writers like
Books (slightly less made-up shit): Most of my reading these days,
too many to list comprehensively. Some faves from the last few
years - Beak of the Finch, Most Oliver Sacks Stuff, A Field Guide
to Microbes, Square Foot Gardening, anything about biology,
complexity theory, particle physics, natural history, puny human
history, your mom.
Movies: I don't really watch too many movies these days but some
favorites: anything by Errol Morris, 32 Short Films About Glenn
Gould, Smilla's Sense of Snow (book was good too), Harold and
Maude, Miyazaki, most of Chan Wook Park's stuff, 2001, Amores
Perros, Y Tu Mama Tambien, Big Trouble in Little China, early Peter
Jackson films, the first 2/3s of Secretary, Cowboy Bebop, Science
is Fiction, Pi, etc.
TV: Sorry, TV has let me down too many times with shows that are
good for a year and then slowly go completely flat. X-files and
Alias, I'm looking right at you. I *might* be talked into watching
something on DVD but prepare to have to be persuasive. First Person
and Planet Earth and the random Nova were good though...
Webcomics, yeah I read too many of these: Gunnerkrigg Court, Rice
Boy, Digger, XKCD, Wondermark, Dr. McNinja, Goats, Achewood, Hark a
Vagrant aaannnd like 50 others. I can quit anytime I want,
goddammit! Addendum, now I'm addicted to Homestuck...
Music: Man, I don't even know anymore. Having 20,000 MP3s killed my
ability to coherently listen to music. Is there a 12 step program
Food: Anything that does not contain onions or (shudder) cilantro.
But don't worry, I can eat pretty much any cuisine since I'm pretty
ninja at eating my way around the former.
