Tagging

I just added tags to my blog reviews. It changed the look of my blog! Fun! However, it is onerous to go backwards and keep adding tags. As a cataloger, I know that a controlled vocabulary provides the most organized access to information; however, I know that coming up with just the right subject or label is incredibly difficult. Automobiles or cars? My brother-in-law, a computer genius, has been working at UI-Chicago for years on a human-like interface that will intuitively provide a searcher with the right information for that individual, based on a complex profile. Whoever gets there first will rule the world.
