NZ GLAM

I have just been browsing through some of the suggested sites, trying to think about Web 2.0 in terms of concentration and diffusion. NZ Research is a concentration of research documents from different New Zealand institutions, and it provides access to a wide range of material, that the general public can view - a wonderful tool for those interested in studies on specific topics.
I found Digital NZ interesting, and feel that if I had a topic in mind it would be a wonderful resource. It works by concentrating information contributed by different groups and members of the public, and then allowing diffusion of this information through remixing and mashups. The ability to create your own widgets on this site is another way of diffusing the informtaion.
NZ Live appeared to be more like NZ Research in that it is a concentration of information, although the blog aspect does allow for diffusion though posts and comments.
Finally, Matapihi could benefit through the two aspects of Web 2.0 - concentration of information by contributions from the egneral public (like Digital NZ) and diffusion of information through a blog. I feel RSS Feeds would benefit this site, especially if aspects of wikis were used to allow readers to contribute and discuss different topics, and then be updated on these discussions through RSS Feeds.
Working through the different exercises in this last module has really helped me to see more clearly the link between concentration and diffusion of information, and the way these two aspects work together and affect each other to create the world of Web 2.0!
