This document discusses practical uses of Web 2.0 tools in libraries and organizations. It emphasizes that Web 2.0 is about adopting a mindset of user activity and freeing up time rather than just using specific tools. It provides examples of how libraries can use blogs, Flickr, Delicious, RSS, wikis, Google Docs, Twitter, and other tools to communicate, share resources, and engage users. The document concludes that libraries should blend different Web 2.0 tools together and take control of their online presence rather than remaining loyal to any single tool.
