Not always easy to find articles that concentrate on genre writing/writers but I found loads at Visions which is a webzine by writers at Forward Motion Community which I think was founded by Holly Lisle (who has good articles on her site).
Here's a link to the Vision back issues...

Also Jim Butcher (writer of he Dresden files novels) has a series on the subject at his livejournal (although unfortunately no new recent entries).

You need to scroll down to bottom of journal to find first entry.
