Blog Interdependent Thoughts maintained since 2002 by Ton Zijlstra.
European citizen in a networked world. Based in the Netherlands, living in Europe, working globally. There are no Others. There is just me and many of you.

I write about how our digital and networked world changes how we work, learn, decide and organize. I explore the tools and strategies that help us navigate the networked world. I am passionate about increasing people's ability to act (knowledge), and their ability to change (learning). Key-words: open data, open government, fablabs, making, complexity, networked agency, networked learning, ethics by design.

Since we are also both avid readers, our house holds quite a number of dead trees […]
