TalkToYoUniverse has a really good piece of advice in this article on how you should put your world descriptions and exposition into the background by really emphasizing the viewpoint character's perspective. Filter it all through the lens of the viewpoint character, in other words. In a fantasy novel, I could look over at a clock and let people know that there are clocks. The world description would be in the foreground and readers might notice how obvious it is and how it stands out. Or I could look at the clock and feel rushed, feel bored, note how its hanging from the wall crookedly, running out of batteries, winding down, or even remember my now dead parents. All of that would put the viewpoint character in the foreground where they belong and slip the same piece of exposition into the background.
Very cool article! Not to mention the fact that she is analysing the first scene from reader-submitted novels and revealing the information that a reader might latch onto about the world. Take a read. It's a really excellent idea for a blog and one I'm tempted to poach simply because it'd help me figure out how to slip in the myriad of details that distinguish my fantasy setting from the generic one.
