Hello! I just installed Nostr client on my handphone because I read that it was a decentralised version of twitter with less fascism. So far, it looks good. But after reading your post, here are some things I don't understand:
* Zaps
* Lightning address
* Npub
* NIP-60 ewallet
All of this is techno gobbledygook to me. Do I really need to decipher all this stuff to chat on a social network using my handphone?

We need a nostr CLI equivalent of the "t" CLI twitter client. Get on it Jack. The hackscene commandeth

Unfortunately the roadside hawker stall did not accept crypto or credit cards, so I couldn't purchase my breakfast in rural Indonesia using my crypto assets. But not to worry, they did accept QRIS, which is a QR code ewallet payment method, linked to popular "everything apps" like Grab, Dana and Gojek. So I was able to top up my ewallet with a crypto visa card, and then purchase Nasi Jinggo from a street vendor in rural Indonesia using QRIS payment. It's an extra step and there's a fee (about 12 cents) but I bought a rustic Javanese breakfast in rural Indonesia from a guy who's never heard of bitcoin, using bitcoin. In a slightly roundabout way. But that's pretty fucken WILD imo. 
Today I ate two Nasi Jinggo's for breakfast. One had shredded chicken and rice, the other eggs and rice. Both were spicy and delicious. Total cost for two small breakfasts (or one big boy breakfast) was 14000 Indonesian rupiah. Which is about $1 USD.
