When to choose a 760px width app vs 520px?

hi,

A/ When do you make your application for a fanpage iframe vs a canvaspage???
B/ How about fql vs graph? Which one do you use and why? For example

$friends =  $facebook->api("/$user/friends");

vs something like this fql

SELECT uid2 FROM friend WHERE uid1 = me()

regards

I guess I’m having a hard time understanding what this has to do with Social Media Content. Might this thread be better placed in one of the programming forums?

hmm, maybe you are right. My second question should in facebook API forum. About my first question some of you Social Marketeers must have a theory when and why a canvas application is preffered above fan page application?

like to know your thoughts
