21Publish has just released a free corporate whitepaper on how to use blogs in a workplace environment.

"What Is A Corporate Blogosphere?

A corporate blogosphere is a collection of employee blogs (also known as weblogs) that facilitates worker communication within a company (i.e., within the Intranet).

People create personal blogs using next-generation software, known as "blogging platforms", which are essentially combinations of repository, website, content server, and publishing software. Blogs capture the thoughts of people. One simply writes information in a text editor and then publishes and distributes their thoughts via the web. Readers can view the blogs of others and engage in conversations through the use of direct commenting or creation of blog entries that reference the original blog entries.
