On Meta.Chemistry.SE there is a post explaining synthesis golf the goal of which is to encourage participation on Chem.SE. I think that AskPatents could benefit from a similar challenge.
My vision would be to take ordinary everyday objects that predate any patent system and challenge the community to write a utility claim or two for the object (e.g. forks, vases, wheels, anything else in the ancient world). The community could comment and vote on the strength and weakness of claims and language. Any reputation for the question would be rewarded to answers in the form of a bounty.
Thoughts, comments, input, suggestions, interest?
