Here's some pretty amazing YouTube activism by Greg Hewlett, a blogger, Texan, amputee and, by all accounts, fine blues singer. 

Link for feeds.

Unfortunately, Greg reports that the bill amendment that would have forced insurance companies to provide better prosthetics coverage was stripped from the bill.

While unfortunately not successful in this case, this video is a great example of the sort content activism that can reach a lot of people in a short time.  I probably wouldn't have read a letter about this topic from someone I didn't know.  But I watched this video 3 times.

Good pickin', effective message.  Rock on.
