One thing we understood is the teacher is no more a sage on the stage.Teacher effectiveness depends on the pro-activeness of the teacher.Definitely there are challenges but there are many possible solutions.One thing that comes to my mind right now is to start slow but steady.We can start with a small group with a single course than we can expand the horizon accordingly.
Blogging is very interesting.Edmodo is useful.Virtual learning is challenging but achievable.Wonderful experience overalll!looking forward for more such workshops.
