If you're interested in learning more in person, VanJS (@vanjs) often has node-related content.
And like Rob and Brock mentioned in the session, they're starting up the Vancouver Node Brigade (@NodeBrigade) for a more node-focused meetup.
Now, as promised, links from the session and some expanded notes. All questions, comments, and pull requests are most welcome.
