I have never used social media, because I have children who would not be able to use it effectively. However, it can be useful as it has already the structures in place for an online classroom, for instance, to be created. But blocking unwanted intruders might be tricky. There are platforms that are classroom replicators on Adobe Presenter, but the communication is lagged. VoIP migh be used as a classroom tool, but there is lag time there as well.
