This document discusses different types of corporate blogs and their uses. Corporate blogs can be used for national branding, amplifying marketing messages, and allowing direct connections to online communities. They also allow companies to communicate in a more personal way compared to formal corporate communications. However, companies must have clear guidelines around their blog and ensure it is interesting and does not make them liable for comments. Effective blogging requires monitoring content, seeking feedback, publishing updates, and managing time well. The key takeaway is that blogging is a communication tool and not a solution for all corporate problems.
