After hearing the Team HBV Collegiate Conference presentation on using Web 2.0 and Social Media to campaign for a cause, I couldn't help searching for models of social media campaigns online. I found this: http://stemcellcharter.org/.
Beautifully crafted website. Very unique and tasteful. I've sent out a few awareness "ecards" myself from that site. Something about personalizing that little cell makes it all so very...personal. And that's what social media should aim to do - make a larger cause very personal to each supporter. Pretty animations also help.
I encourage everyone to sign the charter! You DO NOT have to be Canadian. Yay for stem cell research :).
