Social Media, in the classroom?

This is a response to the pros of Social Media in the Classroom. (Read it here: http://campustechnology.com/Articles/2012/01/19/Pros-and-Cons-of-Social-Media-in-the-Classroom.aspx?Page=1) I think these are all good reasons to use social media, but not in the classroom. It should be used before or after class. It can be used in school, at the library, at home, or on mobile. It is a good tool, but it should be limited in the classroom. Using Twitter (or other social media platforms) in class is a distraction. There are too many things on there which will not keep children focused. The classroom time needs to be spent on learning, not digital socializing. Using social media in the classroom comes with many potential problems. How would it be monitored? Students can easily abuse it. There is also the chance of posting something that degrades your character, which especially shouldn't be seen by a potential employer or recruiter.
