Social media in education

For my self I think we could use more tools in the area of social media. But there is a safety thing to use old thing that you know of and could handle. The lack of time and pressure on the teachers is hard today and I think that you must get something back for the teacher to get a frequent use of this tools. It's hard to be in the front, on the "wave", "in the cloud" and all other hype things that com to the teachers.  

Also a clear studyplan and assignments what you want to do with it and how this would enrich the education for the students.
