Yes, i like your shift towards risk/vulnerability instead of visibility. That resonates with me a lot, and is another layer that’s I think more important… And possibly what stops some people from participating in open learning? The risk or vulnerability are difficult or the potential learning is not worth that risk?
I don’t know, though, that we become less vulnerable, so much as we become comfortable in our vulnerability, in allowing ourselves to be vulnerable.
I say this, of course, theoretically, and am not referring to extreme issues like harassment, etc. but talking about relatively low-conflict learning environments and communities, where you may risk criticism, ridicule, or carelessness, but nothing major or truly harmful in ways that are more serious.
