I respect the choices of publishers not to publish in ebook format, but I know that for me, it's resulted in spending about three hundred dollars last year on baen that otherwise might have gone to one of their competitors. If you add in the three people I recommended the site it to, and their purchases, there's about a thousand dollars that Baen wouldn't have gotten. Eric Flint's Prime Palaver, his newsletter on the library, has gone through some of the increases in revenue authors have seen, and I'm not the only one throwing money their way - imagine, advertising helps!
