Hi,
As Leva point out, the Impromtu Networking description is to 'rapidly' share challenges and expectations' - while the asynchronous environment enables a bit more time to think before responding. We sell that in online as something for the introverts, an affordance of online learning. It's an interesting juxtaposition and I'm looking forward to seeing where we go with it this week.
Mini videos are an interesting idea.
