Salut cousin(e)!
I think it's an excellent idea.
My advice would be to have a bit of the following categories:
- super famous aspects or even (true) stereotypes of Quebec.
- less evident, but still widely known aspects
- a few obscure facts
That, not only to create some dynamics, but also to give something to everyone: someone who knows very little about Quebec would find at least the 1st category somewhat familiar, so won't be TOO lost, but will learn a lot of other things; someone from Quebec may still learn from category 3, and thus not get bored.
The topics I would personally like to read about are super various so I'm not sure it will help (history, food, architecture, festivals, museums, music.. pretty much anything cultural would interest me).
