One thing that I find very difficult to relate to is the approach that some speakers use to open their speaches - they enter the stage with outbreaks to the audience like "Are you there?" And when the inevitable half-hearted response then comes, they add a "I can not hear you - are you there?"
It may well happen that it's a method that works if you are completely sure that you have an audience who are ardent followers, in rock concerts and similar settings. Otherwise, it is just trying to kick in a lot of open doors (for those who have the energy to yell "YEAHH!", will probably come along anyway) - but at that very point the previously doubtful are already lost in advance, and the speaker will never win them back.
