That's exactly right. The fact that "wall posts" is in that list gives you a false notion of the granularity of the items in the list. One of those is not nearly as granular as the rest - if you assume that it is, like I did, you guess that "data" means "where you went to High School" or your "favorite movie" or some such, not "everything." Really deceptive.
