As a brief aside, let me say that I think text is great. I like text content more than any other content, but the interactivity of other content is quite useful and usable. Also remember that more text is not always better, based on how people read on the Web . Here are some final words. If your site is all about graphics and design, or programming, for example, then you ought to think beyond words.
Images can be great content.
Also think about allowing users to download materials. Use online demos. Add interactive content. In the very near future, only those sites with both text and non-text content will win. As you would guess, Web content that is interactive is easier to learn and use.
