I'm a current grad student writing a paper on Web 2.0/Library 2.0 and information behaviours. My concern is that while there are plenty of scholarly article (even within the past few years), the impression I get from library Facebook groups is that they are outdated concepts, but I have yet to see anything 'replacing' them, aside from participatory culture. What are your thoughts on this disparity and have we moved on from the 2.0s? Thanks
