The fourth screen

My week left very little time to spend on either of my courses, so you can guess what is in store for my weekend. I did manage to cruise through a number of emails and followed the odd link. This one, oddly enough, didn’t come from the course conversations; it was scribbled in the margin of some material I am using for the IA teaching I am doing this week. The blogger is an educator, apparently in Guatemala, with some thoughtful comments on this Nokia ad.
