Left following comment on T. Scott's post on Open Access 2.0
The "2.0" qualifier is more often used in the context where readers themselves create content in a collaborative manner on the interactive web media. I was looking for this angle in Joe Esposito's article. However, I was bit disappointed as this aspect was missing. There is no 1.0 in Open Access. In fact, Open Access itself is "Access 2.0". This movement is all about scholars making their own scholarly literature accessible to their scholarly peers.
