Teachers and MySpace?

I've been asked by the Journal of Adolescent and Adult Literacy to write a piece as a guest columnist, and I'd like to write about teachers and social networking sites such as myspace.com or facebook.com. In my state (Ohio) the Department of Education has strongly warned teachers not to take part in social networking sites. (See this Plain Dealer article.) But I'm hearing from my students that there is no way they will give up their MySpace/Facebook pages upon graduating. They intend to keep their pages private (if they aren't already), and not add students as "friends," and they feel this protects them. I'd be interested to hear from any educators out there who are still active on social networking sites (or who have an opinion on this topic.) Email me at: wkist@kent.edu
