I disagree with their interpretation of the word "hopefully." It's been used the "wrong" way so often that using it the "wrong" way no longer makes you look stupid. In fact, if you're the kind of person who would call other people on this "wrong" use, you're the one who will look stupid. For not friggin acknowledging reality.
