This is neat. Definitely checkout [1] if you're confused as to how it might be used. There are some good examples there.

These guys seem to have a unique perspective on human-data interaction and sharing. For example, the "Global Quick Add Feature" [2] is very intuitive. It seems like this is something Facebook is very interested in as it's essential to their product. I definitely agree with some of the other comments made here - I wouldn't be surprised if Facebook wants these guys working for them at least as much as they are interested in their actual product given their perspective and understanding.
