As I understand it a "Platform" is the number of readers who would buy your books. I am a newbie, so I may be wrong about that, but I'm trying to learn. I know there are writers' conferences out there that I should attend to teach me more. I just need to convince my sweet hubs to let me pay the money to go. He's a real ROI kind of guy, and I don't blame him. Trying to become a published writer seems like trying to be drafted into the NFL. It's a one in a million chance.
Don't get me wrong. I'm serious about what I've written. I love and care about my novel and I believe in my characters. I really would like to catch the eye of an agent and be published one day.
For now my platform is three sweet people who share this life with me (and one day I'll have a fourth -- when she can read). I care most what they think. If they love it, I'll press on into less certain waters.
