I'll also second Morgan's comments about having multiple publishers. I have eight, four of which I submit to on a regular basis. Two of my editors in particular have polar opposite tastes...if one doesn't like a manuscript, I can bet money the other will, and the books purchased by either of them generally sell very well.
Finally, I rather like having multiple editors because, hey, I'm not a perfect writer by any means. With every editor, I learn something new...either a way to tighten up my prose, a way to improve pacing, or some crutch word I didn't know I was abusing.
Great post, Morgan.
