Facebook has brought with it many ethical grey areas. Teachers need to be cognisant of the fact that social networking sites are available to a very wide audience. This has ramifications on more than one level.
First, teachers must consider what information they post on their profiles. There is a stark difference between Facebook and Hotmail, and it seems to me that not everyone really understands how public Facebook can be. Because of the public nature of social networking, teachers must consider their professional reputations when either communicating or adding information to their profiles. What might be fine to say to one or two friends via email is not okay when it comes to writing on the walls of friends or contacts.
Secondly, teachers must be careful as to who they include as their 'friends'. Teachers should not be 'friends' with students and must be careful to maintain that professional distance. Having social contact with students could easily be construed as a breach of professional ethics. I have also heard some argue that it should be accepted and that as long as the communication between teacher and student is of a professional nature, it should not be viewed as unprofessional. I tend to disagree. In my opinion, teachers and students must not have contact that could be viewed as social in nature. This is not to say that teachers with students on their 'friend' lists are necessarily unprofessional, but they need to consider how their actions are viewed by the general public.
