it is difficult to google those so i have chosen to make a general list. they are generally more useful for their particular topics and are opinionated so they actually can be interesting besides the actual information:
- things and stuff - a lot of topics
- xah lee - a lot of topics
- everything rumi knows - anime, imageboards, and other stuff
- compendium of personal ignorance
- everything anon knows
- everything shii knows
- esarr lorebook
- gwern net - science, etc.
- cat-v
- kill-9
some of them are not update anymore but it does not matter cause novelty preference is not a good way to learn any topic (looking at you self-help book sellers)
feel free to recommend any and give better description than i do
