Updated Facebook app for Android might be checking up on you
It is interesting that the Facebook Home app says that it "requires no special permissions to run," which probably indicates that the launcher combines with the Facebook app to run. It is unknown at this point if the information is being "retrieved" only when requested by the launcher, or if the running apps data is kept every time you use the updated Facebook app on your Android phone.
The information is most likely anonymous and while there probably is nothing in it that could damage one's sterling reputation, those prone to conspiracy theories are going to be upset anyway.
