I had this revelation a few days ago, while playing.
There repeatedly seem to be questions surrounding what to do about stats that characters are less likely to use, due to purchased special moves. In my mind, resolving this at the social level ("hey dude, can you mark a different stat?") is fine but prone to edge cases, especially in instances where you partially substitute stats (like how Charismatic allows a Hocus to manipulate with Weird but still have to use Hot for seduction; or instances where you normally don't use a stat at all, but then get a new move that calls for that stat specifically).
Here's a new suggestion for how to handle this:
<b>Fuck what stat you're actually rolling, as far as determining if you mark XP; mark XP based on the stat you were originally supposed to roll.</b>
This has a number of advantages:
1. players and the MC can mark whatever stat they like, without worrying about whether you ever roll that stat
2. when marking others stats, you actually can think about "I wanna see you be Hot this session," without having to know which stat the other character uses to do Hot things
