Ripping off Clay Shirky's book Here Comes Everybody, he points out that sharing sites like flickr allow groups of large size to collaborate effortlessly around some tasks (his example is people taking pictures of the Mermaid Parade in NYC) without having a boss or even knowing each other, on Flickr through tags. More tools like Flickr could supplant some of the hierarchy in large or medium size companies. Why shouldn't a company be able to be a large group of individuals that self-organize like the people working on Linux have?
