Is this really new at all? Seems like Jupyter rendering on Github is already a version of this, without expiration of the notebook and having to buy a license to a proprietary product and get sucked into the Wolfram ecosystem. Yes, Wolfram invented the notebook, but just seems like hubris to now claim they have invented putting notebooks on the web. Interesting idea, perhaps a fast follow. Really wish Wolfram would either open source the front end or innovate something that makes it worth spending money on their closed ecosystem.
