Breaking onto the e-book scene.

I was on the phone with my mom last night and we were discussing writing. Now, like I've mentioned before, I've long held this fantasy of becoming a best-selling author. I don't mean to say I want to make it a lifelong career, but it would be wonderful to just be a one-hit wonder, like Margaret Mitchell, Harper Lee, J.D. Salinger. I'd be perfectly happy just to have something published though; that's when my mom and I started discussing this recent craze of e-book publishing. Really, anyone can write and publish an ebook, and make money off it. And here's the thing- I have an idea. I haven't had an idea for anything since like grade 4. And it's a good one. I just did a web search on the topic and nothing similar came up, so I might have something here- and I can't help but be excited! I should probably begin my research, though, before someone else comes up with the same idea...
