Very cool for multiple reasons! The first is that it seems a lightweight and straightforward approach to launch first and thereafter iteratively improve, e.g. using Zoom to push live video to Cloudflare. Secondly the content, while all Cloudflare-related, seems useful to learn about internet infrastructure, etc.

Perhaps the elephant in the room is "what's next"? Seems like it could at least become a Twitch competitor, if not also to YouTube if Cloudflare is able to figure out the monetization, privacy and copyright aspects.
