For all you Kindle users out there, Amazon.com has just started a new @Author Questions and Answers forum in which participating authors can be asked questions about themselves and their books. Any Amazon member who has purchased items from the site can ask, reply to or read existing questions to and from participating authors; and all visitors to Amazon.com can view current questions or answers on author pages.
So far, participating authors for @Author Questions include Ted Dekker, Timothy Ferriss, Marie Force, Barbara Freethy, Steven Johnson, Robert Kiyosaki, J.A. Konrath, John Locke, Elisa Lorello, C.J. Lyons, Debbie Mack, Brad Meltzer, Scott Nicholson, Susan Orlean, Deborah Reed, and James Rollins. Also, many other authors whose books are sold on Amazon.com have their own author pages, and many include contact information.
Kindle users can initiate questions by highlighting a passage in a Kindle book by participating author, and typing “@author” followed by the question, and using the Tweet/Share option on their Kindle. Readers can also visit the Amazon Author Page to post questions and read responses.
