I'm interested in a service for creating or inventing things in a collaborative way. For example, consider using human-based genetic algorithms to create daily news shows, perhaps in the style of this site: http://www.newsatseven.com (but using people rather than computers). As another example, one might build a service where users invent board games. Again, this could be done using human-based genetic algorithms. Users of the service would be able to modify rules to try to make a game more fun. A fitness function would take into account how popular various game variants are among players. Note that users of such a service need not be programmers: the domain is sufficiently restricted so as to make visual point-and-click rule creation/modification possible.
