To be more specific since I phrased poorly and most are misunderstanding my intent:
If you have a raw global feed you get vile insane shit like borderline CSAM, animal torture, etc; stuff that I would bet 99.9999% of people all do not want to see. Unless you are a super freedom oriented person with at least rough knowledge of how nostr works, if that’s the very first thing you see I understand why nostr seems unappealing.
To be specific: I do not see being an echo chamber as an issue at all. That’s just the initial crowd the platform most appeals too.
Luckily I think most people onboard to Primal, learn and then try other clients, and thus don’t have this problem, but it does happen on some other clients.
