The beauty of zaps is that you can make someone smile and feel appreciated for a price eqivalent of a single Skittle.
You can do it instantly and for anybody in the world who has a Nostr account with a connected wallet.
At first I didn't really understand why I would Zap notes. Looking back, it surprises me, how naturally it came as a habit to send a couple sats for for good memes or thought provoking posts.
As a conclusion, even if you don't understand why would you go through the hassle of getting a LN wallet and connecting it to your account, I highly reccommend doing so. It costs literally nothing in terms of money and close to nothing in terms of time.
