“Cross-community collaboration could be improved by adhering to a few principles:

Minimise vendor lock-in. You’ll only get cross-pollination if you make it easy to come and go.

Check for prior art first. The problem may have been solved before, and it’s worth joining forces on existing efforts in any case.

Be open-minded to other approaches. There are great ideas in all communities.

Listen to the little guys. They’re the ones you’re building for!

Decouple and share core modules. Anything from your UI logic to your bridging code could be handy to somebody else!”
