I just realized how often I use the Amazon "Look Inside" feature (other booksellers have similar functions) not as a reader, but more as a writer. So often we rely on second-hand advice about what works or what doesn't, what's selling or what isn't. But with a totally free, totally convenient "Look Inside", we can get first-hand knowledge of how the books on the best seller lists are being written. We can't get novel-length understanding (like, we won't get a great idea of pacing or plot construction or certainly not of resolution) but we can see a lot about writing style. Possibly this is something everyone else takes for granted, but I thought I'd mention it, just in case. Does everyone else use "Look Inside"? Any great epiphanies gained through it?
