Something weird i've noticed with accessing XML and JSON feeds using javascirpt is that access is often denied (for security reasons I guess...).
Chrome says: XMLHttpRequest cannot load graph.facebook.com/100001263589003/feed. Origin fiddle.jshell.net is not allowed by Access-Control-Allow-Origin.
As you can see in this script: http://jsfiddle.net/sikko/RvQVX/2/
graph.facebook.com/100001263589003/feed?callback=? will work
and
graph.facebook.com/100001263589003/feed will not work
Why ? and how can I figure it out, that an argument such as callback for facebook is provided by the API ?
Why ?
Your JS library is probably switching to use JSON-P (cross domain hack that requires the co-operation of the target site) instead of XMLHttpRequest (subject to the same origin policy) when you include callback=?
in the URI.

Read the documentation for the API
