If google starts with app thingy then expect script kiddies and profile hacking, for which Orkut is already suffering from it. There are groups on orkut waiting for open G+ doors to run their script kiddies. Nothing will remain private or secure in such case. Using opensocial apps on orkut is so risky i don't see it'll be any secure in G+. Oh and i hate any social network using excessive flash/ASP combo, i hope G+ uses minimal of these two ugly ladies. 














My answer - Privacy issue between 2 people and privacy leak done purposefully inside one network with billion profiles for the sake of ad money/search quality is totally irrelevant.
