Week 15, Read a few perspectives on Web 2.0, Library 2.0 and the future of Libraries

According to Wikipedia, Web 2.0 is the term used for web applications that facilitate interactive information sharing and user centered design, and collaboration of the WWW. According to the Library and Information Science Wiki Library 2.0 provides new tools to make the library space (both virtual and physical) more interactive, collaborative and driven by community needs. It encourages collaborative, two-way social interactions between library staff and customers. Web 2.0 covers whole Internet and Library 2.0 is a smaller scale to library services but both were developed for a very similar purpose. I have one problem with LisWiki's statement "both virtual and physical." I agree that virtual space offerers increasingly interactive access to our patron but not in phisical space. Can someone explain what this physical space means? They, the yonger generation, have grown up with the Internet, virtual community. They demand participation and usability on the web. Missing those capability on the web sites might loose popularity quickly. Haven't we already see this trend in every direction we turn?
