Jamie Rubin's blog series[4] is pretty good, too.
I personally just create atomic (single-topic) notes, with tags in the YAML front-matter, and store them in a folder structure along the lines of the Johnny Decimal System[3]. I store checklists, procedures, howtos, concept summaries, cheatsheets, and a daily log stored in a YYYY-MM.markdown file.
I don't have any comment on the blog post in the article, because this system works really well for me. Obsidian is extensible at hell, but I'm not spending all day looking for new tweaks, I'm just writing notes. Also, since notes are just files stored in directories, I have all sorts of shell/Python-scripted automations and shell aliases to quickly do stuff.
