Pat cracked a lot of jokes, and of all the authors I've met, he wins the award for funniest...though I will say the fantasy book reading crowd is a pretty easy audience to get a chuckle out of. Guess we're just a carefree bunch. Pat fielded a lot of questions, and the event definitely had a "hangin' out with Pat" feel to it despite the massive amounts of people. He also read the prologue, from Wise Man's Fear, took some more questions, read us some of his poetry, told stories, took more questions, and signed books.
He mentioned that he anticipates the third book will be out in 100 years, and added that it could come out sooner than that, but probably not for a couple years. Some other subjects his discussion touched on are buying the rights to Firefly, his extreme hatred of spoilers, child rearing, and the world of The Four Corners of Civilization, which may or may not be flat.
He also discussed how the Kingkiller Chronicles went from having all three books finished, to needing years of rewrites. Rothfuss said that when he wrote the books ten years ago, he thought they were totally awesome. However, back than he referred to himself as a "feral writer"; not part of a writing group and had little formal training. Now, with improved skills, and hindsight, he said that some parts are still awesome, and other parts need rewriting, in some cases lot of it. What impressed me was his dedication to writing the best possible book, no matter how long it took him.
