Just a quick post today to point people to Lance Olsen's website. Olsen is a fiction writer who's done some very interesting things the past few years, and I count him as one of my personal favorites. He runs the gamut from experimental, s/f, and mainstream. His most recent novel Girl Imagined by Chance is a must read for anyone interested in postmodern fiction.
His website Cafe Zeitgeist of course primarily promotes himself and his own work, but he has a forum that's good to check out from time to time. A number of writers post there, sometimes to promote themselves, sometimes to solicit submissions to a mag or anthology, and sometimes just to raise an interesting question about writing or art in general.
