Dead-ends are extremely nice for people who want to limit traffic near their homes. The only people that need to access the road near homes within a dead-end street are those people who live on that very street. It keeps the area quiet because it keeps people away.
The opposite goal is desired for web sites. Designers of web sites are like socialites who throw fantastically large events. They want everyone to come by and check out the situation. It’s about being inviting so that more people participate in the event, which justifies Lynch and Horton’s (2001) dictum of no dead-end pages in a site.
The solution is simple. Provide links back to the homepage. Add links to other parts within the site’s hierarchy. Invite people to other parts of the site so they can benefit from the other instructional materials that exist on the site.
