Here it is at last: the Selected Papers Network.   Given that social networks already exist, all we need for truly open scientific communication is a convention on a consistent set of tags and IDs for discussing papers.  Christopher Lee has developed software that makes this work.  Try it out!  

What's cool about this system is that it's federated.  Instead of “locking up” your comments within its own website—the “walled garden” strategy followed by many other services—it explicitly shares these data in a way that people not on the Selected Papers Network can easily see. Any other service can see and use them too!
