Stacy - congrats on getting people reading your blog. That is the first challenge and you've met it. I'd suggest you start by asking people to comment on your posts. Questions that will have a short answer may work best, but I'd go ahead and also ask for their option (do you agree or not, and why; which do you prefer; what have you tried that worked). It may not happen over night, but keep working on it. And be sure to respond to people who reply. You don't have to respond to each post, but a few general responses (thanks for the responses everyone) help people realize that you are actively engaged in your blog, not just posting.
Good luck!
Gladys
