I'm not really sure where this goes because it can be used in both fanfic writing and non-fanfic writing. Mods, if you feel this belongs in Fanfic Related, please move.
Anyway...I found this really cool webite. It's called "Flogging the Quill." The owner of the site is a professional editor, and in blog format he discusses things writers can do to improve their work. What's really different about this site is that he accepts submissions from writers which he then will use to demonstrate his points if the writer gives him permission to post the segment of his or her story.
I've gone through a couple of examples and he really seems to know what he's talking about.
