The video will be on YouTube later. I think NJB puts his videos up one week after the Nebula version?
fwiw though Nebula is not “a random site”. It’s the creator-owned platform that NJB and a bunch of other YouTube channels are on that helps give them a more reliable income source than the fickle YouTube algorithm, while being far more affordable and practical for the end user than supporting dozens of different individual people on Patreon.
