During the discussion of the last three days, a lot of us showed the need for a good definition of social media and furthermore a workable subdivision that would be linked to eLearning.
If you look at wikipedia on social media you can see a subdivision of the apps, but it is not related to eLearning or to the goals you might want to reach in research.
Do any of you have an idea of how this could be grouped? Or do not you think this needs to be grouped?
