What are Audiences used for?
Audiences have two purposes:
1. Targeting questions
You can attach an Audience to a Question to limit who is eligible to be asked the Question.
2. Question response segmentation:
Regardless of what (if any) Audiences you attach to a Question, you can retroactively segment responses between different Audiences. You could, for example, ask a very simple question like "Are you willing to give us a quick testimonial" and then segment responses between your Free Tier
Audience and your Paying Users
Audience to see if your paying customers are willing to give you testimonials.
