I have both, and I find my YouTube home page way more diverse than Nebula. Nebula is an invite-only clique and they invite people who look like them. YouTube, for me, has a lot more British creators, a lot more people of colour, a lot more women creators, a bigger diversity of topics and subjects, a lot more deep technical stuff. Nebula is a lot of American guys discussing movies and politics, with only the very recent addition of Token Brit Tom Scott.

I'm yet another person who only got Nebula for week-early access to Jet Lag, and I think if that particular show ever went away or took an extended break, Nebula would be struggling. I find myself watching something on YouTube most evenings, I rarely find myself on Nebula when Jet Lag isn't on.
