Where's the Open Science?

"[M]y thoughts turned to open science. I haven't discussed the prospect of running any projects in an open way with any colleagues or funders, and I suspect there would be major difficulties, but there's no harm in thinking about it at this stage....[T]he list of "active" practitioners on the Wikipedia page is discouraging - not exactly a vibrant field. Of course, there may be many projects not listed there, but it's not exactly encouraging or likely to convince my colleagues....Open science is an iterated prisoner's dilemma, which is a messy and unpredictable business. Too unpredictable for most people to try to build a career on. Thinking about strategies which are likely to be successful leads me towards the concept of an open science community rather than unilateral complete openness - a long term multiplayer collaboration. Does such a community already exist? If not, how do we build one?"
