The essence of Library 2.0?
I feel that Farkas makes a very important point in this post. The needs of the user should always to be kept in mind. Their requirements should define what Web 2.0 technologies are employed. Regardless of how cool you might think your Web 2.0 system is, if the user cannot or does not use it then it is not meeting its purpose. Having said this, I think there does need to be some leverage of Web 2.0 technologies to allow library staff to interact with patrons to find out what they want and how the service can be improved.
