There's very little I might want to add to the article, except to say "I told you"
This paragraph in particular caught my eye.
"Facebook owns the material on the site, including teaching notes and, potentially, research, says Lawrie Phipps, manager of the users and innovation programme at JISC. He has already advised a couple of research groups to take research notes off a site. While there are plenty of new technologies that lecturers can use in teaching, such as discussion groups, wikis, or Second Life, social networking is not one of them, he says, unless it's restricted to an institution's virtual-learning environment. "I'm on Facebook and I have a laugh with friends," he says. "But, if it comes to academic work on Facebook, it's totally inappropriate.""Read that final sentence again,
"But, if it comes to academic work on Facebook, it's totally inappropriate."
