Found this interesting. It brings up the point of boundaries in eLearning. I can certainly respect a teacher's desire to not be connected to the classroom 24/7. A teacher should be able to set his/her own course policies. My course email policy allows for student emailing and the possibility for a response in the evening. If I am expecting learning to happen after hours (aka homework), I need to be as available as reasonably possible to the students.
I wonder what the future might be in terms of eLearning and work hours of teachers. Could it be reasonable to give a teacher a few hours off in the middle of the day to in exchange be available to work with students in the evenings?
Exploring Google Plus for MS, but it is not looking good, major hold up with the age restriction, having some kids on G+ and some not does not appear to work well
