I am more and more drawn to the work of Damon Centola on the spread of 'behaviors' through networks. I would like to substitute "behaviors' for literacy and begin to apply Centola's work in the classroom. He has a new book coming out on Monday and I have put a talk of his on Vialogues so that we can annotate that: https://vialogues.com/vialogues/play/44449

Aside: When an annotated space reaches a critical mass I think we need summary behaviors or further highlighting and notification procedures. Kevin has already done so in one post. We might call these emergent writing or emergent behaviors.
