Not that I'm saying you're using it wrong, but I think you might be using it wrong.

Global is fucked forever, and will eventually morph into an algorithmically curated wasteland because the current hellscape was unmanageable, as all social media global/semiglobal feeds seem to.

I think nostr is best suited for you to talk to people you already know, not to build a following out of people who discover you, or vice versa on global.

Build a "good" follower/ing list, which is subject to an unfortunate chicken and egg hump of bootsrapping a followed/follower list.

High quality posts are low frequency, you aren't likely to stumble across them on global anyway, as they are badly hurt by poor signal to noise ratios (in which I count antagonistic bitcoin posting, PV posting, jerking off about how nostr is surely going to change the world guys). I trimmed all that out of my feed and even when including replies, I see a few posts per hour max. I think the gossip UX is tailored to this relaxed form of browsing and posting, where there is a clear "I've caught up on and replied to everything in my feed" point. Huge props to its author for this decision, it encourages what I think is a more grounded, less terminally online method of online interaction. It turns nostr into a resilient usenet-style medium (though I am one to talk about usenet, having not been around for that).

All that said, I'd encourage you not to quit using nostr, just to alter your usage patterns and expectations. It shouldn't be used just like how you use twitter, something I think a lot of the slicker more mainstream clients and users are pushing it to be. It is different, and can be in reality different, but the onus is on you, the user, to allow that to happen through your different expectations and use.
