I'm not sure how much benefit Twitter/Facebook/Linked integration is. For most people, those are already channels they're familiar with and are able to easily reach out to, to find people to learn/study with. You'll have a big list of people who are taking classes. A feature that suggests people to learn with would be helpful. The big challenge is bringing people together. If I'm studying the same course at the same time as someone I don't know, that doesn't do me much good, but if you can connect us, then you've filled in a big missing piece. I don't know that you need to build tools for that (I can chat, skype, email, etc on my own easy enough, but what I can't do easily is find others taking the same course at the same time).
