There are a couple of reasons why I read outside my main genres. Mostly I just like to shake things up a bit when I feel myself getting a little bored with the fantasy and sci-fi genres I read. It doesn't happen often, but sometimes (especially with urban fantasy) I start to feel like I'm reading the same thing over and over again.
Another reason I read outside my genre is recommendations. If I'm recommended a book from a reader I trust or I see my GR friends giving rave reviews to a story that I wouldn't normally pick up, then I'll give it a try.
Stories in the young adult and new adult categories used to be outside my genre. If I hadn't decided to try something new, I would be missing out on a lot of truly awesome reads.
