Mindmapping one of the primary readings (Kozinets, 2010) has enabled me to outline a temporal and physical landscape of the online communities and the ethnographical research into them the author describes and pin it to the walls of my lifestream by the four corners.
Creating the map merely by quoting and grouping what seem to me to be salient points has helped fix them in my mind and will hopefully act as an aide-memoire for future reference. The map has a link to the Kozinets article, but could be improved by linking to the other papers.
