I found this on a non-profit tech blog, but I believe it’s applicable to any organizational blogging community.
In the first phase, ideas are crowdsourced from Twitter, RSS feeds of other blogs and previous content is compared with Google Analytics to gives insights into what your audience likes.
The second phase is topic generation, Ideas can originate from exciting company or industry news, or editorial opinions on topics already out there.
The final phase is content creation. This is by Community Managers, or if your company is small, staff members who are really passionate about the topic.
Google Analytics is great to see who viewed your page, but user comments and contributions are what make your blog part of a community. Linking to other blogs referenced or social sites can increase awareness and readership. In this diagram Comments are shown to be equal to the blog itself.
