The Networked Student Revision B

Thank you for more valuable feedback on the Networked Student Diagram. A special shout out to Jon Becker for this visual suggestion.
Cindy Lane suggested that coworkers be added to contacts. She reminded me that many older students have part time jobs or internships.

Here's the update with their input and a few of my changes. I removed the subcategories under social networking and placed it under RSS. You'll see that the diagram is actually starting to look more like a network with RSS as a separate category, but also a subcategory of Information Management. I changed Direct Communication to Synchronous Communication and connected it to contacts, as well. Any more ideas?
