Here are some straightforward heuristics and checks for identifying "advanced" technical users on Nostr, based solely on how they have configured their profiles:
- They leverage NIP05 to map Nostr keys to DNS-based internet identifiers, preferably to their personal domain rather than something like nostr-check.com or alby.com.
- They leverage NIP39 to link their active Github profile.
- They use an LN address that references their personal domain.
- They have a public key with a vanity prefix.
This does not imply that if an account does not meet these checks, the human identity behind it does not possess above-average technical knowledge; however, the opposite is likely to be true.
These are just a bunch criteria that came to mind; feel free to add additional points in the comments 😊
