Hi Dave,
I agree with the thinking on the Personas. I think they're beneficial as they personalize the web literacies for users, and in a way help situate the knowledge, skills, and dispositions of learners as they work within the frameworks we've defined. Of course my understanding of the Personas, or how they play out in this work is limited as best. I think there are far smarter people than me in the group as it applies to the role of Personas.
In terms of the frameworks and branches that you've defined...I think it looks great. I don't like the label and focus of the "exploring" strand, but I can go ahead with it for now. I posted about this in last week's thread. As far as "protecting" is concerned, I go back and forth on that as well. I'm not opposed to protecting as a major strand, and I think it puts a line in the sand about how important we feel it is.
I don't entirely believe that "identity" should be placed beneath protecting...even though this is one of the reasons why I think protecting might need to be pulled from the major strands. I postulated last week that purpose, identity, and sociocultural factors should be considered as each nesting within each other and surrounding the strands. This is largely informed by the RAND heuristic and work by Bronfenbrenner. You can read more on the discussion threads I left here in Google Groups last week. The graphic that I drew up and shared is available here:

In effect, I would see the schematic that you shared (with or without exploring/protecting) with the various nodes being surrounded by the purpose, and then the identity, and then the sociocultural factors that motivate the user. I think these are very important and offer us latitude as we discuss identity, security, etc.
Much of this is all motivated by the discussions we had last week...and Carla's thinking that it should be a 3D model.
Just my two cents...
