Publisher Websites/Blogs

The publisher link list was getting rather long, so I've removed it from my blog and made it a page.  I've also added a small explanation of what some of the smaller presses publish, for those who haven't heard of these before.  If you know a small press (or ebook press) I'm missing that publishes SF/Fantasy, comment it and I'll add them to this page.
