I like this summary of social media by Doug Ray. Clearly it's a bit tongue-in-cheek but it's pretty accurate.
So I don't under-estimate the difficulties involved in encouraging people to switch social media platforms (I haven't done). But with everyone in the institution having a Google account it seems like there's an opportunity.
So, a couple of questions:
- Which other HEIs are using Google Apps for Education?
- Are any using Google+ well?
