Generally, I think more posts = more info = good for town. But that is more about public, in-thread posts. Night chats can be double-edged. If you are fairly certain of the alignment of your chat-partner, great. Otherwise...
In this specific setup, I think N1 private chats are possibly less useful. Past that, they become increasingly useful. My opinion though.
I've been turning this over in my head and I still don't get why this would be the case; mind explaining?
Probably just a different meta than I am used to, but this community seems to be quite confident of their D1 reads. I tend to not be confident of much, until I have solid flip/mech based info to start really digging into & making the pieces 'fit'. This is all based on my meta and POV, which ties back to the first paragraph of the post quoted.
Basically, if one is confident in their read of the player targeted with a night chat, great. If not, you are giving a potential scum a more direct method of influencing your reads.
Blinks Neat. Reminds me of how I saw NQT in a 3-way private chat, him town and the other two maf, fall into this beautifully.
If I were in a private chat with a maf, I would expect to get awesome clues because they are literally trying to influence my reads.
Far as I'm concerned, anyone do nearly anything. I get info from it all.
In this specific case, there's potentially mech benefit involved. For that reason I'm not thinking, "ooh, I can better probe X with a private chat!" or even "Ooh, collaborating privately with surely town X is gonna help!" or even 'well, X and I don't get along great, so I am definitely not gonna private chat with X' because to me.... this is potential mech goodness with a side effect of 'oh, and a private chat'. Which has its own benefits too.
But... I never think 'uh-oh. So and so will influence my thinking, I better not'. And it is weird to me, though I see evidence it exists, that others do.
I'd more slingshot around the person's intentional gravity. Like.... flying by the sun? That's not 'fly into the sun, oh no destruction don't even consider that'; that's 'fly near and get some neat path and acceleration affects, whee'!
It's like an expected 1:1 connection between 'attempt' and 'attempt worked'. Meanwhile, I'm over here like an aikidoist, hoping an enemy throws a punch so I can do even cooler stuff with that than I can if I have to start the fight too.
Except with the private chat potential benefits, I would prefer not to give not-town the mech benefits, so I do wanna be careful there.
