Nathan Bransford's blog is all about the publishing process, what literary agents do (and how to find them) and all those little (and big) things you need to know and good if you want to get published.
For a taste of Nathan's blog, have a read of Ten Commandments for the Happy Writer, and browse from there. I particularly enjoyed his statement
Writing is not an excuse to neglect your friends and family. Unless you don't like them very much.
What do you think of these "commandments"? Do you keep them?
