Yes, and where a post was theoretically open to other characters to join (an Order conversation, for instance), it could be challenging to get a word in if another player was having their couples or characters talk amongst themselves because sometimes you'd stumble into something that seemed like open conversation but was really planned out and so the independent voice could take the wheel off a conversation.

I found this challenging when I took up Ron, actually, because all the other Weasleys (at that time) had the same writer. There were times when Ron became the odd one out in his family, and that grew organically out of the way play happened--this writing dynamic shaped their interactions.
