Your customer
The Customer page is your own notebook about the person you're trying to reach. Two things about it surprise people.
It doesn't change what BuzzRobin collects
Only your value proposition does that. You can fill this page in beautifully and it won't bring back a single different post.
Nothing fills it in for you
BuzzRobin doesn't write here, and it won't treat what you write as evidence about your audience — it answers from real posts instead. So start from the posts, not from your guesses: ask BuzzRobin in the chat what your audience actually says about their hopes, what gets in their way and what they keep asking, and put what you learn here yourself.
Then what is it for?
Keeping what you've learned in one place, in the words you'll use when you come to write to your customers.
