Use: http://graph.facebook.com/24407945#this . It's your data space, so 
you can use identifiers as you see fit, in line with the world view to 
which said data space subscribes :-)

Example of pattern put to use:

1. https://plus.google.com/112399767740508618350/posts/91458DKChnr -- 
controlling a holistic digital representation of my profile via 
owl:sameAs applied across Facebook, G+ and other data spaces

2. https://plus.google.com/112399767740508618350/posts/54JNqCkqBFY -- 
same as above, but using http://vizualize.me/kidehen data space as focal 
point .
