Liked (& boosted) because I do whatever I want.

There are millions of people who can't afford zapping so their likes (& boosts) should still be appreciated.

Now, what if we can set the like button to zap (a tiny amount) as well, without the need to interact with the LN wallet?

Yes, the #nostr client would have to act as an custodian but I wouldn't mind to fill it up once a day/week with a small amount, like I do with WalletofSatoshi.
