Waow, quite a collection you got here. I don't really have a website where i maintain such list, so i will say some from my selection:
- nadeko.net This person hosts a lot of various services and knows his stuff while keeping it otaku enough.
- Frutiger aero archive I wouldn't say i'm too much of a nostalgic person, but the owner is incredibly nice and the archive quality and dedication is golden.
- tane.us (does it counts?) the website speaks for itself.
- tengu.space this person has good tastes and a nice website selection.
Also, some others: pixelde.su - lavenderfield - dinpixels.neocities.org
Maybe i'll add some later.
