Way back in 2009, Automattic released the P2 theme, which has been used to power most of our communications and collaboration since then. A lot has changed in WordPress, in themeing, and in wider web application development in the intervening years. We’re currently deep into the process of building the next generation of P2, which we’re calling o2. Learn about what’s different, what’s new, what works and what doesn’t. Hear about some of our plans for the future, and how we’re morphing WordPress from its server-side roots into powering a dynamic, flexible, front-end heavy web application.
