I think that maybe I've found the solution to the notes shouldn't have titles, but actually sometimes they need titles problem. Instead of a full on title, which looks weird next to a bullet point, just use bold text for the start of the sentence.
I noticed Politico does this in their newsletters and I think it looks quite nice. Sort of breaks up the wall of text, giving your eye something to focus on as you skim. I did it with the previous note. That one actually turned into a blog post. So that was quite nice. #
