I can see that, Kevin, though I think they might also make sense for other attendees (I welcome hearing). However, I agree that for anyone else it might not serve as a useful interpretation. I largely started doing it for myself as a way to keep sufficient ‘cognitive load’ to keep my mind from going off on tangents, but they’ve turned out to be some of my most popular posts (for whatever reason). And I once was pilloried because it was claimed that they were no more than a graphic version of an outline, but they actually can have loops and cross connections that are much harder in an outline (e.g. they don’t have to be directed acyclic graphs, in theory speak). Though I don’t try to make those, sometimes I must. Anyway, understand if they don’t work for you.
