"I do believe that making one's book free remains an effective way to reach new readers who might not otherwise take a chance on your book.  I've had a number of positive reviews from readers who said they liked my book but would never have downloaded if it weren't free.  I do not agree with the argument that an author who makes his book free is inviting bad reviews from those readers who are trying a novel that is not in their preferred genre and may be less inclined to like it.  I believe a good book is a good book, and anything you can do to attract a new reader is worthwhile."
