Amazon sales would say otherwise....
When Amazon says that Citadel has a salesrank of 2,675, that means there are 2,674 books in all categories currently selling better. Keep in mind, these are people who actually paid crazy deadtree prices. I got all of these books directly from Baen in an ebook bundle for just $15 a month... and I had them a month before they appeared in dead tree format. Granted, I would love if Baen had authors like Vernor Vinge and Iain Banks, but I find myself reading and buying a lot of Baen books simply because of the ebooks being DRM-free and the prices being so low.
Here are the books Baen published in January, 2010, with Amazon salesranks as of today.
Original publish dates are shown in parenthesis.
