I've done that, but I was remembering some posts (e.g. http://www.eff.org/deeplinks/2010/04/how-opt-out-facebook-s-...) that claimed that was insufficient. It seems it depends on how much you want to block; even if you opt out of instant personalization, the API will still let apps slurp some data through your friends (though not data deemed private), unless you've also explicitly blocked that app. The main thing missing seems to be a way to block all apps except a whitelisted set. You can blacklist apps, or you can opt out of apps entirely (there's a setting to turn off app access completely), but you can't block-by-default and then whitelist.

Hey there. I'm Austin Haugen, a product manager on the Facebook platform team. If you opt out of Instant Personalization by following the steps above, you will never receive an instantly personalized experience on these sites and we also block the sites for you, so when your friends arrive your information will not be accessible. This was a change we made in May based on user feedback.
