My message in a bottle to Bill Gates

Scoble hits it on the nose again, but I get the feeling he thinks he's the first to think of this. He's not, there's magazines on the newsstands right now already touting the idea of "microaudiences". Content creation for ultra-niche markets is going to be the next big wave. Blogs, Podcasting ... it's all just the tip of the iceberg. There's a killer app waiting in the wings. I don't know what it is yet, but the moment I hear about it, I'll be all over it.
