This area can be used to deal with minutia and character(s) specific topics without holding up the main game thread.
If a PC is interested in having an extended conversation with an NPC that likely wouldn't have any major/direct effect on the rest of the party, just create a thread in this section and start the conversation. You can even tag or invite other players to join with your PCs, and all of the interaction would be in-character. The benefit, as I mentioned before, is that it provides an additional opportunity to role-play without slowing down the main game thread.
