A note on faceted tags
Why namespaced facets beat flat hashtags once a site holds more than one kind of media.
Flat tags collapse under mixed media. #travel returns forty photographs, three
essays, and a project, with no way to ask for just one.
Namespaced facets fix that: place:winnipeg is a place, medium:digital is a
format, status:seedling is a maturity. Each facet browses independently, and
each value spans every collection.
