By way of a little reminder to folk such as I just how far behind the curve we are, I recently discovered the existence of a fair-sized and well maintained Facebook group for the book Ending Aging, the Methuselah Foundation and Strategies for Engineered Negligible Senescence (SENS) research. 900 members isn't to be sniffed at; you'll need a Facebook account to see it, however. As I understand the way Facebook-like social networks operate, a group is a way to show your affiliation to a cause or ideal, a repository for links, files and other resources of interest, and a place for discussion. A web site in miniature, contained with the social network, in other words, and which can be used in much the same way in support of advocacy and activist goals. Social networks like Facebook are one part of the ongoing process of lowering the cost of advocacy, making it possible for more people to meaningfully support a cause with small investments of time. When the cost of making a modest difference is close to zero, everyone who so desires can be a part-time patient advocate for longevity research. This can only be a good thing.
