As I have said before and I will say it again, social media is one of the most influential things in our lives especially in our generation. It is where we learn almost everything. But, to my knowledge, there really is not anything that combines social media and education.
If there was a decent platform that could connect students all around the world and still focus on education it could be really effective. I have been trying to think about how it would work though. It would have to be almost like a social camino. Where everything you need to do is available and also you can communicate with other students and it is fun.
There was an app that I saw advertising all around school that sort of did this called sesh. They marketed the shit out of their app. There were shirt, backpacks, shot glasses, bottle openers and a lot of other free stuff. 
But the idea of the app was for students to be able to share and collaborate on homework/test/anything in the class. It was kinda an easy way for students to cheat and share assignments. But I really liked the idea of it. It claimed it was a peer to peer way of setting up tutors instantly, which is honestly a really good idea.
But what I imagine is something a little different. Not focused on tutoring, but rather some way for students to share what they are learning and discuss it with other students. Personally, this is the best way I learn. When I talk to my friends about what we are covering in class I solidify what I am learning and find it easier to comprehend. If I could create a platform for students to do this with each other it could be very helpful for those students who do not necessarily learn in typical environments well and also it would allow me to make $$ which im definitely trying to do.
