Great, Microsoft - But What About the Commons?

Photosynth is undoubtedly amazing. But this video indicates that it's even more powerful than previously suggested; specifically, it talks about using public pictures on Flickr to create not only detailed, three-dimensional images of the world, but also to use any tags they have to provide transferable metadata. In other words, it's a product of collective intelligence, that builds on the work of the many.

That's all well and good, but I do wonder whether Microsoft has given any thought to its responsibility to the commons it is making free with here....
