A few weeks ago, in September, the Open Knowledge Festival brought together a world-wide community of people working on all sorts of "open": open cities, open design, open government, open science, open hardware, open education, ... and of course: open development.
As one of the main topic streams, the open development track was packed with presentations, discussions, panels, workshops and a hackathon.
There are many new ways to let citizens, organisations, governments and companies work together, and share knowledge and information using internet and mobiles, to help solve some of our biggest problems.
How do we make the data and information meaningful for the groups we want to empower with these new tools? How do we create new services, new business models, and new ways of campaigning?
