Hello Brian, I had a question. To allow users to reply to comments, I've structured the Comment struct to have a toId and fromId property. I was wondering if it's ok to store the comments in firebase like you've done in the video or should the correct way would be to do some sort of firebase fanout? If the latter, how would I go about approaching it?

Thanks.
