I'm curious to know what blogs and other online resources exist that might inform philosophical engagement with cities. Before I get to the shameless plug for my own (recently-inactive-but-soon-to-be-revived) blog, this one has been of interest to me:
This is how the "collective" describes itself: "Sustainable Cities Collective is an editorially independent, moderated community for leaders of major metropolitan areas, urban planning and sustainability professionals. We look to aggregate content and provide resources for all who work in or are interested in urban planning, sustainable development and urban economics."
My own blog is The Ethics of Metropolitan Growth: www.metroethics.com . I plan to start contributing to it again, soon, riding the wave of inspiration from the PPN conference.
For those of you interested in the Occupy movement, there's a great blog where philosophers are invited to comment and discuss: http://occupyphilosophy.blogspot.com
