The social part is difficult. I did attend a Coursera Coursera and at the beginning I though, cool, so now I make a study group. They have a dedicated forum for that. So I said, look, here's my study group and I got more feedback than I thought, someone even nearly begging to get in. ;) Then I created a Google Group and posted it in the thread. Guess what: 3 people joined the Group, one was active. (So 2 in total including me.) Lesson for me: when suggesting a study group, have the Google Group link ready. That said, I think the social part is fine, we have social networks for that. Users just need to learn how to socialize online. This is becoming more important everyday even outside Coursera and friends.. Tutors would be cool, but IMHO they are not necessary for successful learning. I remember a dutch math professor saying basically: "I am unnecessary, you just need to ask the right questions." I.e. if you ask the right questions, you will find the next steps best case by yourself.
