exposure

So I'm a new author trying to make a name for myself. How do I find my audience? The ebook world seems to have a catch-22: I need reviews to get my book onto sites, I need to get my book onto sites in order to find reviews. For other authors out there, how did you get started?

You may also want to post this query in the Authors' Hangout. I know this is the How-To Board and your thread is perfectly appropriate here, but the folks who hang out on the AH are probably better qualified to help you.

Good luck!
