First just want to say Li that your app is cool. Good job.

Indeed it appears that their opinion of 'open data' has shifted.  
Facebook refused to list the FOAF Generator, which Mischa mentions, in  
their application directory as they were concerned about having  
'their' data exported from Facebook for use by 3rd parties. You can  
use it here:


With the above app you are able to export your entire social graph  
from fb, thus capturing all your relationships in RDF using FOAF. I  
guess that with the Open Graph Protocol you can't get such information.
