Most of my favorite books aren't conducive to fanfiction, so I read almost entirely Harry Potter fanfics on this site. I enjoy browsing for odd pairings and talented writers, both of which are increasingly hard to come by. If I eventually start organizing my life, I may take the time and acquire the cojones necessary to write and upload a fic of my own.
Music: Indigo Girls, CAKE, Dar Williams, Brandi Carlile, Ani DiFranco, M.I.A., Joni Mitchell, Deathcab... anything good.
Authors: J.D. Salinger, David Sedaris, Barbara Kingsolver, Wally Lamb, Edward Albee, George Orwell, Virginia Woolf, J.K. Rowling...pretty much anyone fucked up, although I especially connect with dark, depressed authors.
Poets: e.e. cummings, Robert Frost (sometimes), Anne Sexton (sometimes), Pablo Neruda... and more I can't think of.
Movies: The Brave One, The Sixth Sense, The Hotel New Hampshire, Amadeus, 9 to 5, Nell, Sybil, Best Little Whorehouse in Texas, Women on the Verge of a Nervous Breakdown, Desert Hearts... and more I can't think of.
