Hey, no problem! The Kindle Service is great given its giant market share (I think roughly 80% of all eBooks are sold on Amazon), but that also means you have to fight 10x as hard to get seen. There's little to nothing that Amazon will do FOR you to get your stuff seen and purchased, so most of that is entirely up to you. Blogs, Twitter, Facebook, Reddit, Commenting in larger Blogs...all of that theoretically builds your platform from which people will recognize you and your writing.
But I must emphasize (with every fiber of my being) that this is still a crapshoot. Most of it is being in the right place at the right time. All you can really do is be diligent and dedicated, honest and likeable, and hope that your scattershot approach will improve your chances. I'm still trying to figure it out myself
