Bill Gates, Mark Zuckerberg, Sheryl Sandberg, who next? The global leaders of tech are taking on the most viral - and chilling- charity campaign to date by dumping buckets of ice on their head in order to raise awareness for Lou Gehrig's Disease. TechCrunch posted an article lining up all of the tech leaders who have taken the ALS challenge so far, each of whom helped contribute to the tens of millions of dollars in donations. So far, the organization has seen 2.4 million videos (and counting!) of #IceBucket challenges posted to various social media sites.
