Apparently filter.nostr.wine is now moving towards a monthly subscription model [1]. Personally, I don't like recurring payments, especially for relay nodes. But if anything else, I think that's just more incentive for me to run my own node.
Speaking of nodes, I think nostr is still quite a way away from having that "just set and forget" setup that you would normally have from Bitcoin Core.
I've been looking around for some relay nodes last night and it looks like most of them are still either a bit faffy to run or they rely on some docker magic to be user friendly.
Early days, still.
