Memes & Memos
In the past six months, I've been asked to watch the Social Media Revolution video below several times. If you haven't seen it yet, it's worth the watch.

I also came across its sister video, Social Media ROI, also below. Both videos were created by Erik Qualman, author of Socialnomics: How Social Media Transforms the Way We Live and Do Business and its corresponding blog at Socialnomics.

When I first saw this video, I questioned some of the stats. If interested in checking the sources, Erik has outlined them on his blog here.
