Nostr only vlogging is overrated, and to be frank, those who scream and shout about it have massive YouTube audiences and hundreds of videos on platforms other than Nostr. The correct path, I reckon, is YouTube clips as adverts, but Nostr for 'the whole thing'. This way you bring people to Nostr. I will be uploading entire lessons to Nostr in a week, when I'm back from my holiday.
