Thoughts on having a sub-key:

I would like to explore a nostr job finding marked place like LinkedIn and Upwork together, but because we want to use Nostr and the private keys to log-in and create a Job seeking profile.

The problem I see right now is when using relays at the moment, employers could easy see on your pubkey all your free time activity postings (maybe less good)

It would be amazing if there were some pre-stats on your profile like a trust score etc. but not all your personal data.

I guess there could be always an option to choose if you want your profile to be visible.

So I would need a sub-Key connected to my private key in order to have my nostr profile in a potential job market place or Shop selling.

Then this sub key is your Job seeking profile with all your sub data saved on the relays.
