This paper was bit different than the others we have read so far. It presents a different perspective while showing the inefficiencies of traditional cognitive science when it comes to information visualization (info). But unlike other papers this one presents a theoretical framework for Distributed cognition. Personally this paper was bit difficult to digest and required reading some part over and over again. I was also thinking about the practical usability of the framework because as of now it is not fully developed.
I liked the use of basic examples throughout the paper but at the same time it made it difficult to generalize the concept for a broader use. Since there hasn't been much research in the field of cognitive side of visualization, at the moment this paper looks more abstract without supporting implementation. Also it does not provide much support to why DCog is more effective framework than the traditional one for information visualization. But as a whole it is a good paper to read in order to start thinking in a new direction something which is not in practice yet.
