Creating a Teacher's Online Hub

The image below is of a chart that I developed to use as a slide in a presentation that I'm giving next week. The full presentation, which I've done before, is about creating effective teacher blogs and websites. This image will possibly be a new addition to my existing slidedeck and I'm looking for feedback. If you have suggestions for making it better or you just think it's a lousy diagram, please leave a comment.
