internet.artizans reflects on the usefulness of open data:
I'm inspired by the idea that nuggets of opened data could seed guerilla public services, plugging gaps left by government, but i don't see any of that in the data.gov.uk apps list. The reasons aren't technical but psychosocial - the people and communities who could use this data to help tackle their own disadvantage and marginalisation don't have the self-confident sense of entitlement that makes for successful civic hacktivism.
The groups that really need it also often don't have the tech or know-how to make use of - or even collect useful data - to make a case for anything. People like us, the data and tech-savvy can help.
