Are we confirming or ignoring friend requests from our students?
Because I teach about writing, new media, online culture, and professional communication, I see Facebook as an extension of my teaching. I accept student friend requests because participating online like this is part of my pedagogy. Therefore, I seek to model good, professional, ethical online participation and "friending" them and allowing them to see how I manage my online identity as *part* of my professional identity is in my teaching perview. For those who teach in other areas, the purpose and boundaries are less clear. It's up to you. If you do deny them, however, I'd include an explanatory note that you are using Facebook for personal reasons and I'd change my settings so only friends can see your content. I think we're either all in or we have to use social networking spaces privately.
