2️⃣ Common pitfalls: 1. Overemphasis on tokens. A token is a tool that mediates consistency among participants in the system. If the system completely fails when you remove tokens entirely, then you may be overemphasizing the role of tokens. 2. There is no limit to the design space. Two questions are helpful in limiting the design space: What is the powerful concept you want to establish? What is the biggest weakness of this design? 3. Always let the community know the truth. You can't predict what the community will do, and you shouldn't expect them to fix the most obvious problems with your system.
