Prologues usually annoy me, and I tend to skip them unless they are very very short. I realize they can serve a purpose, when used as quick intro to the back story, but at other times they seem like they give out way too much info. In general, I prefer to learn the back story through flashbacks as I read.
Do you like when an author uses a prologue?
Do you prefer when a novel starts right in with Chapter 1?
