However, I think we are starting to value copying above creation. For example, remixes and covers of songs frequently get more play than the original versions. Movies based upon existing franchises or copied story-lines top the box office and blog/news aggregators gain far more traffic than the originating sources. Likewise we often value people who have broad experiences or influences rather than people who have depth in one specific area. This has a reinforcing impact upon the tools we create like RSS, Twitter, etc. We skim rather than dive deep because our culture is increasingly based upon re-appropriating not re-inventing.
