"Pfizer has joined Tumblr for a new blog that promotes the contribution its employees make to people's health. The company is publishing a post each day to its Pfizer365.com site, which is so far home to 45 days' worth of stories."
Access the Pfizer365 site to see how they're sharing stories about their employees to build connections with other employees and customers, as well as help in the recruitment process.
I like the concept. Tell the story of your employees both what they do at and outside work. A human face is brought to this large company. They're just regular folks doing their jobs and helping in the community. While the stories are short and easy to read, they still have a corporate feel about them. In my opinion, it would have a more engaging feel and impact if it was told in a more casual tone or felt like it was being told by the employee.
