The introduction of Calypso has brought the notion of a modern JavaScript approach to the front and center of the WordPress community.

Explain some of Calypso’s core development values that have driven us from the very start at Automattic. How does it look internally and why it’s not powered by any “framework”? How can you get started, contribute, and begin making cool things with it?
