Since we don't have a marketing forums (hint, hint) I'm posting here. I've decided to start blogging while writing my WIP. I want it to be as broad as possible, but always associated with fantasy. The primary focus is to share my experience of writing the novel with eventual fans.
So, for those of you who have written a blog or have considered it, what subjects would you write about?
How frequently would you add to your blog?
What kind of feedback have you received from your blog?
For those of you who read author's blogs, what subjects have you found to be the most engaging?
