So the Staff Favorite list is pretty clear. That's what the staff likes. The New Apps list is not really new apps but what Apple staff likes. So then it is just like the Staff Favorite list. So can you guess what the What's Hot list is? yep it is just another staff favorite list. If it were really a what's hot list then iFart Mobile would be in it. Unless they are afraid that putting gas in a Hot list might be a fire hazard.
