Actually now that you mention it, it might have been that. Anyway, my point being, I was "onboarded" as follows:

1. Hear about Nostr somewhere online (I think it must have been some Youtube video because I had dropped off Twitter at least a couple of years earlier and I don't have any other "social media").

2. Get a couple of client names from there.

3. Log on.

Alby wallet, signing extensions, LN, NIP-05 and all that came later. I was copy-pasting my nsec to log on for a while before all that.
