I don't know how to reach new readers. That I definitely know for sure. I blog, belong to Goodreads, have an author page on Amazon, have a fan page on Facebook, and a regular Facebook page. I also guest blog when I can. I have a Twitter account but I haven't really done anything with it at this point. But in doing all this, I usually only reach the same people. At least it's usually the same people who leave a comment etc. Not that I'm complaining. I'm very, very grateful for those people who read my posts, comment on or like my Facebook status, etc. I'm just not sure how to expand my reach.
I'd love to hear any ideas you might have or things you've done that you think helped :o)
