2 8 June 2001Copyright © Tom Worthington Summary After being involved in pioneering many early web sites, IT professionals have tended to be relegated to a technical support role in web site development. This is starting to cause problems as the scale of web sites and their increasing functionality exceed the skills of graphic designers, librarians, journalists and marketers. The World Wide Web (Web) is a computer system and IT professionals are uniquely placed to provide a deep understanding of how to build such systems well. One example is that IT professionals can show how to bypass the dead-end of current WAP applications and create web sites which work with conventional web browsers, as well as wireless devices using WAP 2 and I-mode.
