Yeah I'm not sure about why he's not here as much, maybe he has more important thing to do with his life. Maybe creating the content and running his business takes up his time, maybe he has family commitments that make that not possible. There could be a multitude of reasons.
I see this attitude a lot on Nostr, that creators should give up their own valuable time to make Nostr a success, and I don't understand it. How many hours a week do you set aside to help market Nostr? Myself, being just a user and a shit poster, set aside none, because I'm just here to have fun. And I don't see how hassling those same creators who actually take the time to at least have a small presence here helps either. Maybe that's why Nostr has relatively little content, and people leave in droves.
