Google Docs doesn't live in the 'document' world. Oh it has similar naming conventions, it uses all the jargon that we're used to and it pretends to be a document ... but it's not because it comes from the 'words' world view. It knows that the words you're gonna edit are, 99.9% of the time, going to want to be loved by many more than you. And being on the Web they know that the world of connected people at your fingertips is massive. Not only is there the list of attractive people in your contacts list but there is everyone with an internet connection!
