I’ve been doing something similar. If I read a blog post / paper, etc. where I learn a lot on a topic I’m interested in, I will catalogue a pdf of it in Obsidian with a tag and an optional note. This makes it easy to access information locally very quickly and I find I learn a lot more because if I forget something, I open up the resource, read the doc and, come out learning a little more. A kind of convoluted version of spaced-repetition but more passive learning.

Granted, I’m aware this probably won’t scale to many topics but a few years and hundreds of notes later, it’s still working well for me.
