Excellent article for conference organizers from David Warlick. He has some great recommendations and links to the works from a conference in California this week.
Conferences are setting up social networks as a best practice. As these handy sites go mainstream, effective use of such networks seems to be increasingly an important understanding for students as behavior on these sites is very different from the "social" social networks in their personal lives.
Encyclopedia Britannica is now free for bloggers from an article on 4/18/08 -- yet another reason for our students to blog. (I have students blogging publicly under pseudonyms.)
This is fascinating, but also interesting to see how Britannica is playing catch up to Wikipedia in the market it once owned. I wonder, which would be more authoriative to you, a wikipedia quote updated daily, or Brittanica updated less often that doesn't display the authors of its content?
