Folksonomy

After reading the articles supplied to further understand folksonomy, I consider the new method of catergorizing everything and anything on the world wide web to be somewhat clever. Let's be honest does anyone know what any of the numbers mean in the Dewy Decimal System? I surely do not, but everyone understands that a picture of a cat tagged "Sparky" is most likely the name of the cat. By using words instead of numbers, I feel like it makes it easier for people to search for what they're looking for. For example, when you use a search engine no one actually uses the SIC codes because before you can even figure out what the SIC code is you have to use keywords to find out what code is appropriate for your topic. In other words, I look at folksonomy as a form of searching for things on the internet using keywords.
