I have to be more clear that our focus is on browsing, and not on search. Search is an important part of every day navigation, but not so much in our context.
When introducing Chalmers’ distinction of semantic, spacial, and social navigation it could be interesting to also include temporal navigation. While I’ve been discussion fading of social texture, I’ve not explicitly discussed temporal aspects of navigation. While not on the same level as Chalmer’s groupings, temporal is still very important. For example on a project my advisor was involved with books recently sold was listed. This list did not fade and the result was that books in this list saw an 20% improvement in overall sales.
When I’m ending up on a taxonomy of social navigation such attributes as temporalness can be discussed alongside those of Chalmers et al. If findings from secondary literature is similar to findings in real world applications these can be discussed as a whole. If there is a gap between the literature and my findings this has to be described.
Studies from the Footprints system was overall not positive in favor of social navigation. Later similar projects found favorable results though. How can this be? Such discussion fits neatly into the discussion chapter.
I need to better describe how I collected data during inventories. In the methodology chapter a generalized instruction is provided. For Flickr, Facebook, and Amazon a specialization of this instruction need to be provided. A reviewer of my thesis should be able to use my instructions for collecting data and hopefully get the same results (ignoring how such services change as new features and improvements are incorporated). I need to explicitly state whether the variables I’ve used are my own or taken from URL structures.
