Tell HN: One Free Startup Idea

Create a forum like hacker news (or modify hacker news) like so:

- when a user mouses over your HN comment, or when a user upvotes / downvotes your comment, you get real time visual or audio feedback.

- make the interface more streamlined, so that you can submit small snippets of thought as fast as possible.

- auto-categorize the front page w/ collective intelligence so you can subscribe to real streams of thought.

What you get is a communication and exploration medium that guarantees enhanced productivity.
