A note about shooting with two cameras: Your editor will need to sync the footage between the different views. To help them do this, clap your hands loudly in the view of both cameras right before you ask the first interview question … yes, just like an old fashion clapboard. Modern editing software has auto-sync features, but this loud clap will help you initially line up the clips.
According to a paper by Duncan Watts and colleagues entitled: "Everyone's an influencer", the most common risk in viral marketing is that of the influencer not passing on the message, which can lead to the failure of the viral marketing campaign. A second risk is that the influencer modifies the content of the message. A third risk is that influencers pass on the wrong message. This can result from a misunderstanding or as a deliberate move.
