How might educational leaders use blogs?

In an ever changing educational climate, leaders would be wise to use the web to log personal thoughts, reflections and current practices at their schools.  While not an expert on blogging, I certainly understand the concept of it and can see the potential benefits.  Blogging encourages professional reflection.  It more or less forces the blogger to think deeper into why they do what they do.  It also allows other professionals to read and respond to the blog, which can expand professional vision.  It should be a win-win for all leaders involved.  Leaders can gain insight, perspective and direction from other leaders that may have already walked through a similar area of challenge.  Professional ideas being shared among other professionals should only serve to broaden the level of excellence in the academic arenas.
