    • Should we aspire to a faster cycle than once every 2 weeks?
    • How active of a role should we play in support of non-Wikimedia uses of MediaWiki?
  • Test infrastructure
    • What role should beta play in the deployment cycle?
    • Do we make people deploy to beta before production, period?
  • Code review
    • What statistics should we track, and how should we go about getting those numbers?
