How to use weblogs as an effective local leadership tool
 
What to blog: Point to changes/additions to your website
 
Web site visitors typically don't mouse around a site looking for anything that's new since the last time they visited. But they will expect your blog to constantly updated.  Therefore, your weblog can be an effective conversational kiosk, alerting people to other parts of your local authority's web site that have recently changed. Let your staff and colleagues know you're willing to do this.
