The "Creepy Treehouse effect" which has been discussed in-depth by Chris Lott and Jared Stein is used to describe what happens when teachers join student social areas - such as Facebook or MySpace. Based on the information session I had with our college students last semester it was obvious how much they did not want us (and I define us as any authority figures) in their space. What they are they most afraid of is the "cyber-stalking" that they expect from their peers, but repel from their parents.
