I love they can just use google docs and publish a "site" like this so easily to share. No html required. I hope Google doesn't start getting political and pulling these kinds of docs.
As such I don't think they have to rely solely on google docs to publish their stuff.
Plus in many ways, it’s also free advertisement for Docs and Google as a whole. “Our platform is so scalable, we can easily make a single Google Doc support the web traffic of almost the entire internet.”
