This is far from a new phenomenon. Hundreds of years ago there were holier-than-thou people standing in the village square, wringing their hands, ringing their bells and talking about how urgent a problem was. They did little more than wring their hands, even then.
In our connected world, though, there are two sides to social media's power in spreading the word about a charitable cause.
According to recent data about the ice bucket challenge making the rounds, more than 90% of the people mentioning it (posting themselves being doused or passing on the word) didn't make a donation to support actual research on an actual disease. Sounds sad, no?
