Hi sanjiovani, jQuery Socialist (the jquery plugin used by social stream to display the social stream) indeed jquery socialist, is only support photo stream. It's because the limitation of the FaceBook Graph API that only allows open access (no auth key required) on the "photos" and "albums" page feeds ( see
developers.facebook.com/docs/reference/api/page/#connections). We're sorry about that
Regarding the pinterest, I can't replicate the problem. I even able to display the pinterest stream on your website. Please check, I have added user jrbrochstein to the pinterest stream option and it displayed properly
