This article is based on my presentation at the Institute of Scientific and Technical Communicators' annual conference in October, 2006. Every now and then, there is a change in the value of what technical authors deliver. These are moments when organisations pay attention to technical documentation. This is because they recognise that these changes mean they can create something that will be of real value to the business and to their customers. In recent years, there have been three "waves of interestingness". The first wave was the introduction of Windows Help (WinHelp). The second major wave was the introduction of the Internet and intranets. This was a time when organisations looked at how they could transfer large amounts of information from paper to online. They were faced with issues such as how users could access and understand all this information easily - issues that technical communicators deal with on a day-to-day basis. I believe we're just about to approach the new wave, which we have called "Tech Writing 2.0".
