Are unit blogs a good idea?

There are a growing number of them out there: blogs created by military organizations (or businesses, for that matter) that serve to provide command information to the public or enable internal communication. These are often seen as outputs of propaganda at worst and, at best, providing no new insightful information. It seems to me that we are just barely scratching the surface of what could be and have some ground to make up in the perception arena.

One idea that has recently come to mind (partly inspired by Prof. Lawson's article) was for a unit-level blog. This blog would be:

• maintained by a responsible and effective writer within the organization (whether that's a company, battalion, or brigade - higher than brigade and we lose some of the "muddy boots" perspective)
• provide information similar to what is often provided to families through family readiness channels but would be tailored for the broader potential audience
• maintain a blogroll of all blogs of Soldiers in the organization. This would provide one way for the Army to keep up with many blogs and could provide interested readers with a broad perspective on the activities of the particular unit

By maintaining such a blog at the unit level, readers would be presented with a broader perspective than they currently can get by looking at somewhat random individual blogs, it could significantly assist in the distribution of stories that otherwise don't get told or are buried in other press outlets, and potentially could serve as a link between official statements through traditional PA channels and the very unofficial stories told by milbloggers.

Is this idea way off mark or is there merit to it? I'm interested in your thoughts.
