I've recently taken on a new job, after 17 years of consultancy. I grew restive at my own weak points, and wanted to outsource sales and management, neither of which I am very good at. I'm now working for Cloudmade, which is a for-profit company seeking to advance the use of OpenStreetMap data. Open Data is very similar in manner to Open Source. It's data that nobody can own, because its value is in the community that creates, cares for, and nurtures it.
