Good morning notes are popular on Nostr because they're part of the #bloomscrolling pura vida algorithm. The people want positivity. The people don't want rage algorithms. Nostr gives the people what they want.

Large part of it is emotional amplification. People share what speaks to them emotionally but sometimes it’s just a pure numbers game. Enough connections x a fairly pleasant non-controversial note = trending. Case in point - Odell’s gm notes
Most people on Nostr recognize what's wrong with legacy social media. It's easy to see the differences between our conversations and community versus the other dark side of the internet.
I also believe many people take advantage of the popular GM notes for both positive and negative reasons. On the positive side, many people participate in GMs and PVs to be social, to be recognized, to be their own algorithm and be heard. As for the negative, I would not be surprised if some people "farmed" GM notes to get zaps.
