I've been thinking about this actually. My content is mainly about the carnivore diet and most of my audience so far is 45+, which makes sense, they're the most likely interested in returning to a healthier state.
So that has me at my dilemma, go for decentralisation now and have a lower impact on the people who could benefit from this or choose to grow an audience there first (I barely started my YT channel) and then switch later on to Nostr.
Also, my content is in Spanish and it seems the Spanish speaking community is nowhere near as big as the English speaking one.
