How can educational leaders use blogs?

I love technology! I seem to always want the newest and coolest gadget. Yet, at the same time, technology can seem overwhelming. I actually started blogging because a friend of mine blogged. She is an assistant principal at a high school in Florida. Her school uses blogs to help keep parents informed of various programs, application deadlines, football games scores and stats, etc. She is in charge of the blog for her school. She said at first it was hard to keep up with, but once the parental support took off, she said it became very exciting to do. I think blogging is a great way for parents to keep up with things going on around their child's school.
