Hey everyone!
Since nothing's been posted on here for months, I thought i'd throw something into the ring. This is the "What's the Big Idea" section of John Scalzi's Blog. It's a series of short essays by various authors on how the ideas for their novels are formulated. There are some very interesting ideas in there.

Hope you like it.
Scott.
