I'll repeat the blog tour idea. You should look up Ashley at The Bookish Brunette. She has a fairly decent following and she's part of the book blogger directory. Not ALL of the book bloggers are a part of it, but they're all basically one big circle and their power over the genre industry is pretty impressive (Ashley herself has about 1,400 followers and she only started her blog this past February, I believe.)
Here's a quick link for you to get to her site easier. She's also doing a thing called Indie Frenzy where independent authors are hosted on her site.
Another thing you could do is get a Tumblr page and post excerpts of your writing (little bite-sized pieces of it.) On
my Tumblr, I do the exact same thing, and while I don't think it's gotten me a whole lot of attention as of now, what I have posted has gained me around thirteen followers. Those are people I wouldn't otherwise have.
I had another idea, but it seems to have slipped my brain. I'll come back and comment if I remember what it was.
