More irritatingly, Google's cache appears to have it available, but says "404" if you actually try to access the cached version (my usual workaround for these JS-only-app-sites.)
Though it's possible to "publish" or share your notes it doesn't look like a well designed use of the platform.
If you are actually editing the content then I agree that using JS makes sense and could be obligatory; but then, sharing/publishing content in what should obviously be a read-only form should really turn it into a static page. It'd save them some bandwidth too, given that readers really do not need all the functionality the JS has. (The app-*.js on that page is over 4MB!) Unfortunately common sense is not so common.
