Two comments:

1. If Twittering pulls a significant number of students into "interactive mode"--and I assume this is what's desired--the situation is clearly not scalable without some additional capabilities. Because a limited number of concepts related to the class are likely to be addressed in the Tweets, it is conceivable that concept recognition and clustering software such as NLM's MetaMap could track those concepts and alert the class leader in a useful way to issues on the listener's minds. This would be in lieu of a moderator and perhaps allow the leader to adjust a presentation on the fly.

2. I would also add to the participation activities: annotation of a representation of the class material (i.e., taking notes). For me and many others, this is a very important part of fixing information in memory, identifying crosslinks with other material, and creating an artifact that is optimized for later review.
