Lifestream – Classstream?

Google recently bought Jaiku, a micro-moblogging site (that’s micro-blogging like twitter + mobile blogging) that also keeps track of when you post to your blog (via an RSS feed) and when you post to your flickr. It also posts a timestamped record of what you listened to on iTunes or Last.fm and what you last bookmarked on Del.icio.us. So they take all that info and put it into a feed or “lifestream.”

Now, I teach 2d Foundations and Drawing… which aren’t necessarily heavy on computer use (all my students keep blogs, use a textbook wiki, photoshop, that’s about it). But I was thinking about how great it would be if I did have a feed, or if we all had access, to a “classroom feed” or Classstream that would work something like this:

10:14pm Allison finished 15 thumbnails for homework
1:42am Anthony posted link to article on Fred Wilson
9:37am Bob posted to blog: Principles of Gestalt
12:00pm Johnny needs feedback on sketch for assignment – visit blog
3:30pm Anthony posts picture from Toledo Museum of Art
and so on…

How could you see this useful in your class? In an online class?
