For security purposes, the Orkut sandbox opensocial calls will only
return information about users who are whitelisted for the sandbox.
This is likely why many of you have been seeing empty information
returned from the fetch VIEWER_FRIENDS calls.
Please friend other whitelisted developers, or register additional
test accounts to build a graph of whitelisted friends. An Orkut
community has been created to help find people working on the sandbox
to friend:
