Help your potential matches find common interests.
Authors (because picking individual books is too hard): Neal
Stephenson, David Mitchell, Max Barry, Haruki Murakami, Chuck
Palahniuk, Neil Gaiman, Steven Erickson, Brandon Sanderson, Robert
Jordan, Patrick Rothfuss
Movies: Alien, Aliens, Die Hard, Primer, Willow, Fight Club, Last
Life in the Universe, My Neighbor Totoro, Ghostbusters, The Thing
(80s, not 2011), Midnight in Paris, Drive, the first 3 Indiana
Jones, Matrix trilogy and so on. I am a huge fan of movies
generally speaking and will happily watch and discuss them.
Music: Placebo, Juno Reactor, Autechre, Infected Mushroom,
Shpongle, Keane, The Mars Volta, Nine Inch Nails, Tool, A Perfect
Circle, Nightwish, Mira, Love Spirals Downwards, Portishead,
Sneaker Pimps, Fiona Apple, Massive Attack, Muse, Lustmord and
plenty more. I've also been on a 90's "alternative" kick lately,
thanks to the accessibility of music on Pandora.
TV: Seinfeld, Six Feet Under, Freaks and Geeks, Undeclared, The
West Wing, The Wire, old school Simpsons, South Park, and probably
some others are my favorites. I've been losing interest in a lot of
ongoing shows I used to watch, but there's still probably a dozen
or so that grab my interest every season (currently watching
Misfits, which is everything Heroes should have been)
Foods: Italian, Thai, Mexican, Indian, pretty much anything with a
good heat to it. I am very partial to giant burritos.
Games: (I don't like the lack of this category here, it's 2012,
time to get some recognition as a legitimate hobby) I've owned all
three current consoles at one point or another, but currently I
just play games on the PC. I'm also quite fond of board games,
though too cheap to buy any of the really expensive ones. I also
have a lifelong love of table-top gaming (Dungeons and Dragons,
Shadowrun, Call of Cthulhu, etc).
