IBM: A Really Big Company Newsletter

The world's largest technology company may also be the world's "tweetingest." More than 1,000 employees in various countries use Twitter to talk with both their co-workers and customers. Twitter lets employees demonstrate their expertise and serves as a real-time IBM community newsletter, getting time-sensitive word to the company's global ecosystem faster than by any other means— including IBM's own LotusNotes. Adam Christensen (@AdamClyde) is the IBM manager of social media communications and says Twitter spread through the corporation organically, "There was no top-down mandate. One employee started using it one day and influenced another, and so on."
