John mentions the bad habits that even experienced dancers
          may have while swinging, such as:
           
          - grip, clamp, squeeze, hang, press
              - hold their partner in the wrong place so it is
          uncomfortable
              - use too much strength and try to do silly things like
          making their
                     partners feet leave the floor
              - lean sideways or backwards
              - start twirls too late and when they are facing the wrong
          way so that they
                     end up in the wrong place
        
        I find it pretty telling that this list of habits actually has
        nothing to do with footwork! In my opinion, the reason to teach
        walking swing instead of buzz-step to beginners is that there's
        SO MUCH ELSE to concentrate on. The more things we can abstract
        away, the easier a time beginners will have learning what's
        left. If you're focusing on strange new footwork (and I find
        that buzz-stepping beginners tend to think that the
        buzz-stepping is the most important part of the swing, and
        concentrate more on that than on their frame), it's harder to
        pick up things like giving weight, a proper hold, etc. But
        everyone already knows how to walk!
