User experience is closely related to brand perception, and a fundamental tenet of this is to help users find what they need. Easing search and inviting user participation creates an engaging and successful user experience.
Flickr, a website dedicated to helping users organize and share photos online, allows users to label or "tag" photos. The photos can then be searched or browsed by these keywords. Tagging leads to a flexible, user-built information architecture called a folksonomy, a system that makes information more intuitive to find. Rather than limiting navigation to the site's system, users are permitted to create multiple paths, which evolve as content or needs change.
