Good links on the weblogsInEducation: Weblogs - The Pedagogy of Nudges! site. So far my one completed experiment of weblogs in education - http://friday.editthispage.com - has been very positive and it was a great success. I think the secret is, indeed, to keep nudging the students. That's what I hope to do over at http://www.arspentia.org but it's going to take a bit more nudging ;-)
