Good points

the temptation in this blog is to focus on problems (see my last post), so here's some good practice I'm seeing.

There is some excellent presentation and engagement by students on specific issues and on general interests.  there's some really good chairing.  There's good use of integrating new materials into discussions and blending the online discussions with the face-to-face.  Generally, people seem engaged in the process (even if they are not directly talking), so I'll take that as a marker of interest and immersion.
