I was going to say, I used a sequence diagram last week to wrap my head around a threading situation. I think they are a good way to visually model anything asynchronous or thread based, and sometimes also user interaction flows, and I think UML's bad rep (is that fair to say?) means a lot of developers either are not aware of them or think they must have no value – I consider using them a bit of a secret superpower ;) I do occasionally use ER diagrams for drawing out data models too, but I'm super rough about following the "rules" with both of these. Really just a convenient way to sketch stuff out (usually using PlantUML or Mermaid, as I find it quicker to do in ASCII).
