I've been using #Obsidian for more than four years now, with by my count about 1400 daily log entries and a total of over 7000 pages in my big vault.
There are some people who use this tool for very elaborate hierarchical structures in which to encode all of their knowledge about something. I'm more one to look forward to a blank page every day to start from scratch.
The promise I made to myself is that when I hit 10000 pages in this thing that I will re-examine my choices for how to take notes. I do notice that my daily notes are so focused on cross-linking to other pages that they are way less expressive in style than the blog posts that I once wrote. Links are very useful in Obsidian, but over-linking gets in the way of picking distinctive wording.
