Help Selling Blogs In

One of the attendees from the Boston AMA Blogs: Marketing Beyond the Website workshop is looking for a few innovative approaches to help him sell-in blogs to his management. He's asked for help from the AMA blog community. The following are the concerns that he's struggling with:

- Blogs are time consuming and need a full time blogger to write, monitor comments/trackbacks and manage the bloggging process.
- A board is more dynamic in nature, people have the freedom to post whatever they want. People from the company, as well as, other other readers can respond - much the same as they would via a blog.
- A full-time employee is not necessary to implementing a board. Company saves on human resources.

The company is also interested in developing RSS feeds for targeted segments. Can RSS feeds be password protected so that only specific people are able to subscribe to the feed/or read the feed?

Thanks for your help!
