Node.js Foundation

• Healthy Open Source
  • explicit goal to be a lightweight process
  • concrete ability to scale to hundreds of contributors
  • good fundamental goals
    • transparency
    • participation
    • efficacy
  • ecosystem projects encouraged but not required to adopt foundation governance templates
• creation of projects under TSC explicity delegates authority from TSC to project TC
