Submitted my post-line-edit manuscript. Yay!
The problem (if there is one) with self-publishing is this: it requires a daily gut-check from the moment you sign up until you get the moment you cash your 'break even' check. If you publish through the established system, you get a strong indication that you WILL sell as soon as the publisher accepts your work. With self publishing, you can fool yourself for much longer, and for me, that's been hard. We shall see.
