Haha! What if we had a website where people could post such ideas and discuss them? The process of discussing and refining an idea would make it un-patentable?

Haha! What if we had a website where people could post such ideas and discuss them? The process of discussing and refining an idea would make it un-patentable? That would be an interesting forum for geeks / problem solvers AND would kill stupid/obvious patents as a side effect, and act as a repository of prior art! Since such discussions might articulate at least the broad ideas (even if they don’t get to a specific implementation) this might discourage at least overly broad patents. PS: Did I just make this idea un-patentable by anyone else? :D
