I'm with you, Onenote has a unique niche. My pet theory is that Onenote can be seen by some HN types as too pedestrian (therefore not worth mentioning) because it is so popular yet is looked down on because it is made by Microsoft. MS is often looked down on by linux-first-everything-is-markdown techies because of their 90s and Windows 10 sins.
