Recently, I've come across several great blogs for authors.
It's amazing what you can learn on the web, from the comfort of your home. It's like going back to college. Here are some blogs to check out. Plus there are links to more great sites on each blog.
By Randy Ingersmanson: (he also puts out an excellent newsletter)
By "Miss Snark" a.k.a. literary agent: (advice that you just can't pass up)
By Precision Editing Group: a group of 5 editors who answer your questions directly (I also contribute to this blog every Thursday)
All worth your time! As an unofficial poll, what blogs do you regularly read?
