This looks relevant to Mashable City:

"Twitter bots, aggregators, social software, mobile apps - we use
these things more and more in our daily routines to make our lives
better. But can we also use them to remake our cities altogether? How
can these technologies be applied to transform urban spaces, changing
them from the centralized, hard-coded things they are today into
finely-tuned, fluid, user-operated systems that are efficient,
sustainable and fit for life in the 21st century?
DIYcity is a place where people figure these things out by actually
building and launching applications that address the problems around
them."
