I was thinking, and a good addition to newschoolers would be lessons possibly learned from facebook. in pictures and videos, you could have the option of "tagging" other newschoolers members by their sn, creating a link to their profile, as well as listing their names.
Another thing is the notification system. Whenever someone posts on one of your videos/pictures, responds to your thread, etc, you could be notified near the message/online friends area. That too would be tight.
