A bunch of folks have made posts pointing out discrepancies in the course materials, myself included. Would it make sense if we logged these changes? Add student's blog posts about corrections via RSS to a webpage. That way there would be a single place where students could go to see modifications to lessons, exercises, etc. Students wouldn't have to scroll through all the different posts on the class website, news aggregator, etc. to get an idea for what has changed. Also, this working change log could potentially be a good resource for the instructor if he wants to revise the materials for future classes.
