Facebook Professor

I truly feel that the professor did not intentionally set out to hurt anyone. I am sure she felt bemused by the prospect of teachers using the web to research information for their lessons. How is this any different than the teachers who use to do it the hard way? They still researched information for their lessons. But I feel that if a teacher is going to post comments like these on her Facebook account or any other similiar sites, they should make sure that only the ones they want viewing the material is allowed and all others are blocked.
