Interesting activity. Question: Is this useful in a larger group, or only in a smaller group? The calling-out portion enables people to participate without talking, which accommodates larger numbers; but the exposure can be intimidating – particularly for students, who then may just stay put. Maybe start with "easy" identity groups – sports team supporters? – that people are willing to show? Or would this undermine what the conversation should be about?

The discussion portion may get out of hand in a larger group; may need subgroup formation.

This leads to digital inclusion as opposed to digital divide. Digital divide assumes that information is only accessible to certain areas/certain "categories" of users.

Not really what we tend to mean by “open access” in academia, but closer to “open education” than one might assume. It can be less about the cost of textbooks than about inclusion. And diversity.
