Read your blog Ruchit. I agree with your thoughts on human interaction.

I think in a couple of years we will discover that the key benefit to online education is the ability to consistently deliver high quality instructional content to very large numbers of students.

The social component of learning should benefit from this. My hope is that online delivery of instruction will free up time in the classroom for the human dynamic of discussion, problem-solving and shared inquiry.

It's too early to conclude what are the limits of computer mediated human socialization.It's still a pretty young field.For example, just before something like 6 months , google came out with google+ hangouts, and now some people are cooking together using it, which seems pretty unexpected.
