Earlier this week, the New York Times published an article about Seattle's influence over the nation's book-buying habits. It cites the fact that Amazon, Costco, and Starbucks are all headquartered there, and each has a unique influence on what people read.
I won't go into all that here because the article does that very well. The point I want to make, first, is that any of those major employers would be a good place to get relevant experience to launch your publishing career.
Second is that of course, even though the article shows its East Coast bias, there are also book publishers in Seattle. One in particular springs to mind...you know, Microsoft Press? McGraw-Hill also has an office there. And as with most places, there's a burgeoning small-publisher scene. You can catch up with what they're doing at the Book Publishers Northwest blog.
I'm just sayin'--you can start your publishing career just about anywhere. And this is further proof.
