I didn’t want to repeat what others have said, but I admit that lack of face-to-face interaction is my biggest concern. Not just face to face though – voice to voice as well, my 13 year son refuses to call and speak to his friends and insists on texting them. There is something being lost there. During MET collaboration, I have been so pleased to be able to interact with my classmates via video and voice conferencing. The times I have had to synchronous text chat have been painful for me.
