Thanks for the information. Here's how I'm presently using social media, especially vis-a-vis World University and School.
I post a lot in Google + (at Scott WorldUniversity - https://plus.google.com/115890623333932577910) and Facebook (http://facebook.com/macleod) about World University & School. Check out, with an invitation to join, too, the World University & School FB group: http://www.facebook.com/groups/48753608141/ . And please add your name to World University and School's Google Group:
These posts often make their way to my blog (http://scott-macleod.blogspot.com) under the 'global university' category - http://scott-macleod.blogspot.com/search/label/global%20university - (so, accessible in Google's blog reader, for example) but Google + and FB are more interactive and real time.
I post less to my and WUaS's twitter accounts - http://twitter.com/scottmacleod and http://twitter.com/WorldUnivandSch.
Much of the above is accessible centrally on my web page: http://scottmacleod.com.
World University and School links to many social networking sites (around 10) are accessible at the bottom of most WUaS subject pages in the WUaS Navigation Sections, here, for example in the WUaS Economics' subject : http://worlduniversity.wikia.com/wiki/Economics#Learning_Networking .
Have a good holiday.
