Pawel Szczesny at Freelancing Science has a post considering models of open science, and how best to encourage it. For one thing, he says, it would be helpful to test various models outside the scientific arena: "Principles of Open Source software did not prove to be useful in open drug development. ... Crowdsourcing will not advance quantum physics," he writes. "Open Science in its fullest form is not an issue that scientists can truly solve by themselves."
