Why not turn twitter into a massive brain for problem solving / brainstorming?
A task would be given to the twitter community along with a deadline.<p>The community would then collaborate to complete the task via standard twitter communication.<p>The task could be well-defined such as finding a strong move in a chess game or more open-ended such as inventing a new kind of robot.<p>As for the selection of the task, this could be done by the twitter community voting on proposed tasks.
