I love this feature of nostr.

Dev of client/wallet which I use posts note about new version/improvement.

I zap them which gives information on multiple levels:

💜Reaction: thank you for this post, I see value in it.

⚡Tip: thank you for your work, keep going.

🤝Support: thank you for your awesome software which I use, have some pennies to maintain it further.

Mind blowing 🧠💥
