Very nice. I especially like the structure (What?, Why?, How?, And?) which is shared for every note. Though it has fallen out of popularity, RSS will be useful. Overall the concept kinda reminds me [the morning paper](<a href="https://blog.acolyer.org" rel="nofollow">https://blog.acolyer.org</a>). I wonder if there're similar attempts for other fields (math, physics, ...).
