Ideas For Sale

Create a Twitter account (or groups?) where people can post their ideas for anything. Accumulate enough to be able to create keyword alerts of some kind and approach businesses who may be interested in 'plugging in' to innovative ideas. Be the middle man where if a business likes an idea then they may contact the person for the rights. Businesses pay a low fee for 'plugging in'.

Have a group of 'ideas' people who specifically come up with ideas for companies as well.
