Computer directories are dying. Yes, the complicated, tree structures of hierarchal files and folders that we've long relied upon to manage our information and media are on life support. Well, truth be told, I'm resorting to hyperbole in order to make an important point. Directories still exist (and *will* exist) for the internal functions of our computers. And they'll be available for people who insist on using them. However, they are becoming increasingly irrelevant and inflexible in a world of virtual information structures.
