Depends, depends, depends...in the social/club arena there is the need for people to learn that needs to be balanced by the wish by all parties to have a good time dancing. I don't see, for example, an advanced follow just following a leader all the time, even a beginner who is off and whose basic beat wanders all the place. Here an advanced follow by keeping the basic beat and communicating it to the beginner could be doing a good thing by compensating for the beginners lack of knowledge and skill, and by doing so help instill synchronicity to the music in the leader. At the same time I'm sure dancing that way would be a lot more enjoyable.
