narratives: I think it also depends. in dw rp, replies soften take a while and threads get dropped a lot, so "getting your ship where you can" sounds legit to me.
I also used to think that you "should" only write your ship with one person, but grew out of it, given dw rp.
1:1 RP PSLs might be another thing, cause you can focus a lot more on each other?
