Well, through reading over the past week I've learnt that there are more applications for the the Web 2.0 'movement' than I'll ever begin to imagine.
It is not about new technologoes so much as a new way of using the already available technologoes with it's foundations in end-user participation. The more people who use it, the better it becomes. Apparently the idea of subsribing to pages (for example blogs) is relatively new and significant in the development of Web 2.0. In the past, traditionally web pages were static and viewed by the end- user where they are increasingly dynamic and interractive with 'subscribers' and 'participants'.
As a librarian, I need to embrace and become comfortable with the interactive nature of Web 2.0.
