ObsidianMD

I use it for work, study and ttrpgs such as dungeons and Dragons. It is great to have a graph view to let the dots connected and a place to keep the text in one place with fast navigation.

As an academic I’ve used it for several years to track my classes, lecture ideas, etc., and more recently keeping a record of media consumption, movies, TV series, and novels.

I’d like to get more out of the data in my vaults but I struggle to grasp many of the most interesting community plugins such as Dataview. I really enjoy using Obsidian but suspect it’s challenging if you lack a programming background.

I don't really use obsidian as I already have a very capable markdown editor set up in neovim; but it's a nice live-preview editor for my worldbuilding project where I now basically have an internal wiki because it's been 6 years since I started and some things have gotten way out of hand.

it's not that great for the purpose as I've thrown it into an astro project and it doesn't do full HTML rendering; but it's plugins (like dataview) are insanely cool and they will no doubt be indispensible when I manage to make it do calendar conversion math (for which I wrote a quick tool in rust because I was horrendous at doing the math manually)

I use Obsidian for making notes on papers (+some blog posts e.g. the illustrated transformer) for my research for my PhD - It's very useful. For general note taking and stuff and note taking in in meetings, I use Nextcloud Notes + QOwnNotes.

(and ref domain name, I do use Arch-->Artix on my travel laptop :P)

As a student I use Obsidian on my Arch Linux Convertible. It's great for taking general notes during class and I use Excalidraw for doing Chemistry and quick Math notes :). Also good for annotating pdfs. Furthermore I use it for Art ideas, Recipes, Short Notes and all kinds of stuff I want to remember

I use it as a second brain and to consolidate my notes for school.

My school notes include half of my undergrad in economics and all of my notes for the MBA program I'm going through right now.

The second brain part comes from all the notes I take all the content I consume about stuff, mostly books, though. I think it's amazing that I can look at notes I took years ago and remember the context of my notes.
