Flickr Toys

What fun! I love that so many users have devoted their time to creating fun and exciting tools that other Flickr users can make use of for their own enjoyment. This is one of the great things about Web 2.0 technology in my opinion: Users take the services in new and perhaps unanticipated new directions, creating new functionalities along the way and making the tools living, growing entities rather than letting them stagnate. These piggyback tools not only allow users to expand upon the original service in creative ways, they also offer new opportunities for their creators to potentially profit from them in ways that were not possible in the Web 1.0 model.
