Yepp good writeup. Some of these I focus on with nostr:nprofile1qqsdr0fnxvmn8hxyz8cwazfm8zu9yt7qmc38ll69nkvsgn8dnej4sxckxm0xe
Also notice how much more I'm on Nostr now as quality of my own app is going up. Becomes more enjoyable, it's long since I stopped posting from other clients.
I also create new fresh accounts almost daily, it's the number one focus: The new user experience!
