I do Dev and manage servers and databases -- I need one place where I can find all my stuff. Googling and going through 15 links for the same issue every 7 months all over again is a chore -- as a knowledge worker. I need to have a base of stuff I can refer to, my own curated knowledge base.

I need the info to be available to me on multiple pcs and even better from my phone so I can refer to common things immediately.

I write down stuff that I know works correctly, but have to use very infrequently -- my tmux config or the correct network config so hyperv will work.

I use Notion for tons of stuff like that.

I use Miro (diagraming app) when I am trying to understand complex stuff for the first time -- where there are tons dependencies and I have no clue what is going on like an existing large codebase.

Text files tend to become very limiting in how you can express and present the information back to yourself in a meaningful way.
