Lost track, new things constantly pop up.
Nostr.band is one of my most frequently used as I like to reference old notes.
I like the simplicity of nosbin. When you think nostr is a social network and see a pastebin replacement it makes you think what else is possible.
Verified Human I thought was a great idea too, can see space for that in future.
CivKit is interesting but I’ve not played with it much. Some of SuperTestnet’s stuff looks very cool too.
Most promising are the ones that use nostr as a protocol to glue other things together. Content + Lightning + Nostr - there’s a shitton of opportunity just there.
Looking forward to seeing innovation around nostr identity management!
