Conceptual maps

I am trying to do a conceptual map of my area. Main authors, conferences and so on. As I am using delicious to record my websites I think it's quite useful to leave this link here.
I have read a lot of different issues:

• User-centered Location Awareness - MIT projects. They show diferent kind of projects with GIS technology;
• Mobile Communication in Everyday Life: Ethnographic Views, Observations and Reflections - I have only one chapter

Everything connected, however different. Well, I should return to work and continue my endless map :)
