Web 2.0: Where will the next generation of web it take libraries?

Web 2.0 has 5 professionals (Librarians) share their expertise, knowledge and views on this subject. All very well said. Overwhelming but needed to drive home the impact of what modern technology has done for libraries and users. Everyone is impacted, whether they be young school children, high school students, college age students, scholars, educators, professors, businesses and/or anyone in communities, they benefit from it all when libraries bring their services readily and conveniently available to patrons. Are we scheduled for Web 3.0 & Web 4.0 next summer? We'll have to find out what is in store for us.
