Great question, thanks!
Hard to tell; I read mostly those I follow, but don't add to that list enough because my client (#Amethyst) makes it hard to review new candidates... Meanwhile, rarely (never?) do I get replies to my appeals for help with the issue...
I'd love to see more long form content, which is my bad because I haven't spent time exploring those other clients...
Finally, I'd love some tutorial material aimed at coders (me) who would like to get a notion of how to try some nostr programming...๐๐
