Good for basis research, horrible as a learning tool, and for anything deeper, due to the site's bias
Internet Archive, as of the 08/24, is still going. If there's an out of print book or obscure movie you needs to watch. Internet Archive and to a extent, the wayback machine is great. Though a portion of books are locked through it's loaning system.
4chan and imageboard culture has been in freefall since Moot sold out. But the Blue Boards are still probably the best place to go to for media reccommendation, with their charts, wikis and so forth.
Fan Wikis
Too many to count, Avoid .Fandom wikis, and stick to ones created using MediaWiki and other alternatives, if possible.
Not as useful as Internet Archive, but great as a comprehensive archive of public domain books
Good site to read up on early modern philosophers
Similar to Early Modern Text, But it's operated by Liberty Fund, a Libertarian think tank
A MIT Archive of Classic Literature
University of Pitburgh website containing a library of folktales and a webring to adjacent sites
Archive of Works by Situationist International
Another archive of Works by Situationist International, Openly Leftcom/Social Anarchist
Big Tent Archive of Anarchist text, Of Social Anarchist Leanings
Wayback archive of Ulillia's website. I found out the guy when Pannekoek2012's Watch for Rolling Rock video went viral. The guy has been going at it, in terms of navigating with his OCD. Which I can't say about a lot of people who have intellectual disabilities, including myself to a extent as a Autist
Bringing you autistic, self-imposed Mario 64 challenges since 2010.
To be honest, I was not familiar with this webcomic until cybershell's 2019 video. Prior to that, it was mostly osmosis. But hey, the comic, particularly from Chapter 1-21 Is one of those comics that is still good in spite of it's flawed art. After that point, eh? Who knows when it will reach the peak that was the Weed Party Arc.
Objectively the best game design related channel on youtube, leveraging material from Famitsu Columns, plus some decent overviews of how Sakurei's games were conceptualized.
Conpendium of links for gamedev relevent sites.
Gamedev resource focused heavily Algorithm and pathfinding
Online Linear Algebra Book, Oriented towards graphics programmers and game developers.
Utena fansite, that is still archiving materials. The interviews alone, are worth seeing. But a lot of it's charm is really felt in web 1.0 stuff like the 2 shrines and IRG, it's original forum.
Nowadays, it's a mixed bag, particularly on the community side of things, a lot of old heads with skeletons in their closest mixing with a lot of toxic younger fans raised on tumblr culture. I'm not Right-Wing/TERF Adjacent anymore, but I would rather to stick my own space in fandom; As I'm a bit of a edgelord comperatively and I mainly like Utena for it broader themes, political/artistic bite, and the characters overall (the things that places it within the Long May 68, and Counterculture), then just it's gay representation or quasi-feminist themes.
Offical website of Universal Gravitation, the Successor to the Tenjo Sajiki led by J.A. Seazer and responsible for singing the Akio Arc Choruses. Useful if you want to keep track of the performances as a Japanese speaker
Archived Geocities Page With Lyrics for a lot of old plays by Universal Gravitation (Circa 1985-1997). Valuable Resource if you have the cassettes or found bootleg rips online; and you need a reference
Asian Crack is a label of J.A. Seazer's, which releases albums and compilations Containing Music from Universal Gravitation Performances.
Angura Research Center is a valuable resource for Japan's Underground Theatre, And by extension, Japanese New Wave. Containing 3 subtitled videos of Tenjo Sajiki Plays like Shintokumaru for example. each of which, has an accompanying article.
The Akio arc page is down, at the moment, but this is still probably the most comprehensive JP commentaries on the duel songs and what play/textual source they came from. Which is useful for translators and those trying examine the songs. Which is important, because it allows you as a viewer/listener to see past the songs as words salads, buttrock or imagistic commentaries on the duels (Where I kind of nominally stand).
Aaron Dylan Kearns has a lot of Hiroshi Harada's stuff archived on his YT. And stuff including scripts related to the Tokyo Grand Guignol (A Theatre company founded by ex-Sitaution Theatre Alumni) on his Tumblr. That said, Aaron is a Hard-Left Socdem, a situationist/surrealist Socdem, but a Socdem regardless. So I don't personally eye to eye as a Market Anarchist/Individualist. (Not in the ancap sense. But in the proudhonian/egoist sense of opposing the forceful leveling/collectivization of one's possesions to the state.)
