Imagine looking at your desktop, where all the menus and files are sitting, and being able to rearrange menu items and add new ones. Imagine making links that open a system view(a window) that you made to organize and view your content. Imagine being able to access your computing environment from anywhere on the internet. This is Drupal, and we access it through a tool like Firefox.
You might be thinking that this is "dangerous". How can we trust having ubiquitous access to all of our content? I believe this isn't a technological problem, it is Human. We have to make systems that foster building social trust in real space, with the people we live our lives near.
