There is more than one way to take part.
Some people may contribute ten hours a week. Some may bring technical skills. Some may bring governance experience, design, research, writing, legal thinking, community building, or simply a rare ability to see the problem clearly.
Ways to contribute
shape the vision and the principles
build or test the first product
answer an open question, or add a better one
write about the coordination problem in your own words
bring a community that is already feeling the pain
review governance and stewardship drafts
contribute to the shared record: decisions, context, commitments
The question
Nobody can do all of it. The question is whether you see the same direction.
I can only show the way. You have to walk there.
