A new software tool Digg combines elements of social bookmarking, RSS feeds, blogs, and more. From their site (via Ulises Umejias):

Digg is a technology news website that combines social bookmarking, blogging, RSS, and non-hierarchical editorial control. With digg, users submit stories for review, but rather than allowing an editor to decide which stories go on the homepage, the users do.

It looks like the building blocks of the different software tools are gradually being integrated into one tool that will facilitate more reading, more writing, and more interaction. It will be interesting to see what sorts of links and networks will emerge from making technology easier and especially more social.

Question: How will these technologies affect educational institutions? Will there be a move from a more authority ranking relational model to one of the other relational models?
