I really like how your iceberg image depicts how the education system affects our ability to participate in PKM.

The 4 categories capture the deep seated antagonism I had as I plodded my way through academia. I've been thinking about barriers a lot as I work with others on social learning in the workplace and integrating social media in their practice. I'm recognizing how commonplace it is for practitioners (including me) to avoid experiences that result in feeling vulnerable. Sharing, learning together, testing out ideas in public etc. means making yourself vulnerable to others.

I'm adding that condition to my list of barriers and work on some probes/activities to help loosen vulnerability conditioning (another product of our Modern Educational System).

Thanks again Harold for your PKM framework. It's helping me understand (and be a better practitioner) the building blocks that make for more productive outcomes.
