- Remove Forebrain and Serve: Tag Clouds II
- The idea behind tag clouds is that users know best. Their actions determine how other users navigate. Their choices leave a trail.
- As tag clouds come to replace expert taxonomies in common practice, carefully constructed hierarchies vanish. In their place is a flattened world where every idea, at any level, is a topic as worthy as any other.
- Instead of a hierarchy based on user-centered classification systems, the tag cloud “hierarchy” is based on raw usage.
- The intellectual problem is that tag clouds create a data world where subtopics are detached from their parents; where the very notion of parent/child relations no longer exists.
- If the site’s goal is to let only the most popular stuff float to the top, then tag clouds work like James Brown. But if its goal is to offer a better way of letting users find any content they desire, then tag clouds are as wrong as the Patriot Act.
- Pure tagging is completely flat data orgainisation.
However, if you allow people to tag tags you allow a hierarchy of data to develop.
- The relationships between the tags are what's important, not so much the tags themselves -- in this way they're just a means to a greater end.

Facets
Navigating within the hierarchy naturally builds up a complex query that is a conjunction of disjunctions over subhierarchies.
- example: facet1=color=[red, green, yellow, blue,...], facet2=scent=[bloomy, dirty, tropical, rainy,...]
