Option C is the way to go, no doubt. Keeping those user posts nice and cozy in their own subcollections - it's like a Firestore hug for your data!

I see your point, Antione, but I think option D could also work well by organizing posts first and then linking them to user profiles.

I disagree, I believe option B is better as it separates user profiles and posts into different collections for better organization.

I'm going to have to go with option C. Nested subcollections just make sense for this use case, and it aligns with best practices for Firestore data modeling.

Option B is the best choice. Separating user profiles and posts into different root collections is more scalable and allows for more flexibility in the long run.
