Another advantage of interactivity is self-generating content . By allowing your visitors to interact with your site they actually create content for you. Script-driven user surveys and forums allow visitors to share information with others and can help shape your site to better serve their needs. Forum or chat software is a great way to do this. A great example of a user-driven site is Slashdot , a news site for nerds which posts short stories submitted by users, and allows users to easily append comments to each story.
Users equate poor organization with poor site design.
Sun Microsystems found that users equate poor organization with poor site design in their extensive usability study of their home page. They also found that users don't want to scroll. It depends on your application. Web pages should be at most two 8.5 x 11 pages in length. Supply both text and graphics for buttons.
