You need to view it in adobe acrobat to view the annotations as the comments I added don't always show up online.

I suppose my blog post will incorporate these sources and perhaps more in considering the impacts of our addiction to social network sites and what might be considered healthy use of these resources.  I'm also interested in our addiction to mobile phones/ tablets/ computers too, but that must be for another time.  I'll focus on social networking for now.
