Let us evaluate a set of pages to see if we can come to a consensus on what factors make a page Good or Bad or Ugly. In addition to cataloging features rate the sites 1-10 with 10 being best. Of course you distance learners will need to discuss this exercise via a conference.
An exercise for students: Select a site, not one on this list however, that you don't like and explain why. Send your comment to the mailing list.
