At the moment I'm a judge in the Romance Writers of America's Rita contest. I love judging because I'm sent 6 to 8 books to read and many are authors I haven't read before. If I enjoy a book I can add that author's name to my list. Because, to be honest, my reading time is so precious I rarely buy a book by an author I haven't read before, or that I don't know personally, or that hasn't been recommended to me.
It's not that I don't want to try new authors, it's just that I don't want to risk not liking a book when I know that there are authors out there who never disappoint!
What about you.... do you try lots of authors or stick to those you know?
