Presented at Online Information 2007, December 5, 2007, London, UK. Weblogs written by employees of a company can be valuable communication and knowledge management assets, providing ways to speak in a human voice within or outside the organisation, to find previously undocumented expertise, and to create unexpected connections between people and ideas. Given their grass-root nature is there something that can be done to maximise those benefits? This presentation starts from examples of employee blogging (based on the results of a study at Microsoft) and then discusses how companies can benefit from it by integrating blogging as part of their knowledge management initiatives.
