What my tokens mean:
- ❤️ love = invaluable
- 👍 like = very important
- yellow medal / mountain of wealth = good but not that much
- doubloon / piece of eight / haypence = doesn't harm
- 👎 dislike = should not be done
- the world burns = controversial issue
I thought about using 💔 heartbreak for stronger dislikes, but I decided not to since it might be mistaken for "more than invaluable".
