How leaders can use blogs.

My principal and I were recently talking about communication, and how he can do more than send out emails that get piled up and overlooked in the inbox of a busy day.  I feel as though some of his thoughts could be put into a blog and shared with the staff in a manner that is engaging, and not one where we think "oh here is yet another email".  He could put his motivational information he sends us as well as the day to day grind of whats going on in the legislature towards education in a blog.  He could set up a blog to share with parents a variety of information that might be engaging to them, and allow them to feel connected to the campus that they send their child to each day.
