Live Posting.

You have a blog on the site, and you can write anything your mind desires there. The poster uses Markdown to style their posts, which means that they can include audio, video, images, quotes, links and so on. They can time it (write fully and post later, or schedule a time and day for when they are to start writing it) or start spontaniously, with those who follow their writing being notified either way.

The difference beign - once you make a new post, people can join as spectators: watch how you lay down ideas and comment on it live, with the poster being able to see them and respond, both in the post and in the comments. The poster has the option to hide the comments, but the brilliance of the idea is the interaction between the poster and the spectators/watchers/whatever you call them. It's the YouTube for writers and poets.

I thought about making it happen, but for the moment it's just on the fringe of my web programming skills, and right now I'll spend to much time coding it. If nothing like this will appear on the Internet when I'm a more mature web programmer, I'll surely make an attempt at making it happen. I think it's a great idea that deserves at least a try.
