Critical Mass vp of experiential design David Armano is a certified social-network celebrity, with a well-read blog and popular Twitter feed. This week, he decided to put his network to use for good—and might have just developed one of the most powerful social-media case studies to boot. Last night, Armano posted an appeal on his blog, and to his 8,200 Twitter followers, to help a family friend in desperate circumstances. He set a goal of raising $5,000 in small donations to help the woman and her family get back on their feet. By this morning, donations had topped $11,000. Social-media mavens are talking new world order, and Armano thinks the response is a powerful testament to what networks can accomplish. "I'm hopeful we can move the discussion from who has influence to what we do with what influence we have," he tweets.
