I don't mind, thank you for your curiosity.
I'm not here for money. I see Nostr as an instrument to enhance Freedom of Speech, a fundamental human right.
That's what I care about, money is secondary. I'm here for social networking.
I think economic incentives, in practice, don't improve the microblogging experience and are, if anything, often detrimental to it.
If I ever do publish some way to receive donation, it will likely allow multiple currencies (not just Bitcoin) and be related to my blog or other kinds of long-form content.
If I write something that you like on Nostr, you can show your appreciation with a like or (better yet) a nice comment.
