Cool! You have the start of session move correct. It is pretty sweet once you get the hang of it. What ought to happen is that players should use it to tell you what they’re interested in chasing. If you have a bunch of threats about Coyote and old gods, and every session, they’re like, “I heard a rumor about the narco vampire lord…” then you need to back burner those old gods threats and start investing where the players are going. It doesn’t hurt to be explicit about it now that you’ve had a sessions and have a bunch of stuff to work with. And if they have a good idea about a rumor that doesn’t fit with anything, let them go for it! Loose threads make great future nooses.
