  4. Facebook Data Team: Distributed Data Analysis at Facebook — job ad from Facebook gives numbers on company use of their Hive data warehouse tool built on top of Hadoop: Today, Facebook counts 29% of its employees (and growing!) as Hive users. More than half (51%) of those users are outside of Engineering. They come from distinct groups like User Operations, Sales, Human Resources, and Finance. Many of them had never used a database before working here. Thanks to Hive, they are now all data ninjas who are able to move fast and make great decisions with data. (via Simon Willison)
