PUBLIC MARKS from sbrothier with tags "navigation system" & usability

Compared to conventional navigation patterns tag clouds don’t necessarily offer a more convenient and intuitive navigation. However, used properly, they can provide visitors with an instant illustration of the main topics, giving a very specific and precise orientation of the site’s content. Since human beings tend to think in concepts and models, it’s easier to get an idea of presented content if the main concepts are given straight away — in digestible pieces, and prioritized by their weight. In fact, the main advantage of tag clouds lies in their ability to highlight the most important or/and popular subjects dynamically which is not the case in conventional navigation menus.
