SN has really been my first hands-on exposure to Lightning. LN makes it way easier to transfer small amounts of money to people, so I've basically been messaging my friends at random, asking them to install Wallet of Satoshi and give me their address. I figured I'd start off with 30 sats, because it's really a technological breakthrough that I can transfer $0.01 to anyone, anywhere, essentially for free. And then send a bit more after.
I've spoken to ~7 people so far, and only one put in the five minutes of effort. Several people were like "why do you want me to install that app?" or "that app looks sketchy and crypto is a scam".
