Internal blogs succeed when management believes their value outweighs their risks and conveys its support overtly. But the risks are very real. Information managers must decide if blogs serve a useful purpose in the company. Do they comply with existing policies on information retention and security? Are they auditable or discoverable? Must they be? And what happens when a blog makes someone look bad? Internal blogging might start under the radar, but it will only thrive with the support of management that considers it to be an asset to the company. This support only comes after information and knowledge management (I&KM) professionals prove, by addressing purpose, policy, and reputation issues, that blogs provide business value.
