I know of some students and even parent who put anything and everything on their Facebook and Twitter pages. It is no wonder that we have a difficult time encouraging what is appropriate behavior. I think as teachers, we have to be very careful of what we put on our pages. I've seen and heard about too many stories where teachers post things that probably should not be there. I try to be very careful with my accounts. I had a weird instance happen just a couple of nights ago. Someone privately got in and synced a photo off of my phone. I felt so violated and I have nothing to hide.
