All content is not of equal appeal. Without entering the realms of sensationalism it is useful to develop hooks to grab and maintain the reader's attention. The content wealth and potential audience of a site is increased with the language versions that are offered. On-line translation services exist like AltaVista's Babelfish or the European Terminological Information System and many are free of charge. But be wary of how you use these.
Nothing can replace professional translations.
Some translation houses offer output directly in HTML format. The Internet is clearly showing signs of becoming a serious multilingual space. The benefits of multimedia material in teaching are well known. The challenge lies in creating applications that have internal logic and are not just gratuitous displays of technical prowess. The usage value of what is on offer is particularly important within the context described above where the service provided is more important than the information as such.
