I also created something similar. People were really interested at first. But we learned after sometime that people loose interest when learning with strangers. We could not retain people after a week of sign up. Although this is bit different so might work. Good luck to people who created this.

Wouldn't part of the point be to introduce people, so they're not strangers anymore, after a while?

Encourage chat/discussion in scheduled breaks?
