I think they'll be showing these comments both in person's wall in the Facebook and on the app's page in the App Store. And also keep in mind that YouTube commenters don't talk like that all the time. It's just YouTube bringing the worst out of them! The same is true for Facebookers (although FB is much better than YT); people's "tone" will change when they know they're writing this "review" for their friend on Facebook (or at least, they know their friends will see them attached to their username). Some people might actually write better reviews (less anonymity), but I think most will write worse reviews.
