# 15 Web 2.0 etc

Web 2.0 is a mindset as well as technology. Tracing from 1.0 (libraries as a commodity that warehoused books) through 2.0 -- and looking beyond to 3.0 and 4.0 -- requires an open mind. Web 3.0 mentioned superstar librarian avatars, but can we move too far into the virtual world? Web 4.0 looks at libraries as a knowledge spa, an immersion in a luxury of ideas and thoughts -- this concept seems far beyond my understanding at this time. What is important is to control technolust -- having technology for the sake of technology. At the same time, we need to be trend spotters -- knowing what is important to focus on.
