This is a good practice. It turns what could be a lesser-version of Wikipedia, where links are just “related” into a semantic why they are related via how they are used.
The link up there to Wikipedia suggests “there’s a note having to do with Wikipedia”, meanwhile a note that is able to Use Full Sentence Note Titles to Crystalize Thought becomes immediately clear with what that notes relationship is to this one. This still allows you to grow, develop, and build on ideas, but doesn’t relegate them to simple topics. This quite literally grows the intersection between crossing trains of thought.
Notes that contain ideas are best fully expressed, notes that only talk about a topic are best left terse.
Side benefit: this is the ultimate form of Distillation. You don’t have to express the idea perfectly right out the gate, they can be added to/refined as a part of Progressive Summarization.
