seems like an ideal fit for the globalization & ethics online course we'll be rolling out in spring 2010. our experiments with drigg were mixed, but there are several advantages to this approach that I think might help. short video responses could be an ideal fit for distributed students.

polls are intriguing as well. once the faculty member is back stateside I'll talk it over with her. could be a good opportunity to try it out in a relatively contained (30-40 student) pilot to see what's what.
