Safe Playgrounds

George Siemens responds to Peter Tittenberger's The Strength of Garden Walls. I wonder if there might be something else at work here besides educators' tendency to think in outmoded terms of "my stuff" and the attendant view of education as something that ought to happen behind closed doors (though I heartily agree with the assessment that the notion of intellectual property is something that needs a hard look--and I would add that what is problematic here is the idea of knowledge as "property" or commodity, an attitude that grows out of an acquisition mentality).
I've been thinking that, for me and (if it's legitimate to thus project) for students generally, a safe place to air ideas within a smaller community, for the peer review of people I trust and whose counsel could keep me from making large mistakes, would be immensely valuable en route to publishing those ideas, suitably reworked, for the whole world. In fact, I think if I were designing a learning experience for students that featured Learning 2.0, I would make that a central feature in both content and practice.
