The document discusses the concept of Web 2.0 and why librarians should engage with it. Web 2.0 allows for two-way communication through social software and user-generated content. It also turns the web into a platform for developers to create applications. While some librarians feel too busy or overwhelmed to participate, engaging with Web 2.0 can provide professional development, expose one to new ideas, and benefit teachers and students. Getting started may involve using an RSS reader, joining online communities, or exploring ways students can use Web 2.0 tools.
