Yeah, I have a lot of fun, on here, but it's mostly just me and my frens.
And I communicate with most of them on other channels, as well, so Nostr social feeds feel more like a playground and info board, than an essential service.
I actually am mostly interested in OtherStuff, so this doesn't really bother me, that much, but the social feed use case is the main catalyst to run relays, so the feed dying out endangers the relay network.
It's like we're all off on side-chains and nobody wants to mine.
