What an “idea” is? Simple, clear and consistent concept that allows sharing, suggesting and browsing to be as easy as possible. An idea as a text string of no more than 140 characters.
As ideas are expended and built on, descriptive text, images, video and audio can be added, along with comments and ratings, but always around a key, central 140 character concept.
