I've never understood the nostr-only strategy (rather than a mainly-nostr one, since you can use other platforms to drive traffic to nostr), but I think X is sort of melting down into bots, spam, and idiots asking grok stupid questions. Most of the people who post there don't look at their replies, anymore, as it's so much trash. It's just a place to post your own stuff, really, like a board. A free website.
