I promote on pinterest, twitter, and g+. About once a month, I ping all the new ones and the ones that are withering on the vine. I never use my personal FB. Friends get sick of that after a while... unless it is to promote on a page for writers or your business page. Then FB can be helpful. I use a promotional line on my emails that directs any emailer to my home page, if they click on it. I also send traffic from my personal blogs. Sometimes I write on squidoo. I send traffic from there, too.
