Movie Keywords Analyzer (MoKA), like Flickr, lets users apply tags to non-text content, where they make sense to support free-wheeling descriptions and in my opinion complement, rather than compete with more structured taxonomies. Not quite faceted navigation, but it’s still nice to find, say, movies that feature drugs, dream, death. Obviously there’s a lot of tagging left to be done, I’m curious about how fast and accurate it’s going to be.
