It seems that everyone is talking about Web 2.0. This new vision of the Web enables greater interactivity, more user control of information, radical personalization, the development of online communities, and more democratic management of information. Supporting technologies include blogs, wikis, RSS, podcasts, tagging, XML, and Web services. However, the author argues that Web 1.0 have not yet fully achieved. Thus, basic Web functionality needs to become ubiquitous towards building Web 2.0 concepts and technologies. Here, he also presents his observations based on the many hours of looking at all types of library Web sites as one of his long-standing projects which is maintaining the lib-web-cats online directory of libraries. Recently, he conducted a survey to learn how well library Web sites conform to coding standards using a listing on his Library Technology Guides site (http://www.librarytechnology.org/arl.pl) and the W3C validation service in an attempt to validate the main page of each of the 123 members of the Association of Research Libraries (ARL). These libraries all have very sophisticated Web sites and should have technically proficient site administrators. Surprisingly, there are only 21 out of the 123 Web sites passed validation. This only shows that there is a need to improve the technical practices so that the current generation of Web sites relies on valid XHTML and CSS coding standards will provide a stronger footing towards next-generation Web technologies.
