Thanks. I have only one page that uses javascript, which is my artblog (Might phase that out when I have the time). It's kind of my policy to use as little javascript as possible and keep things as basic as possible with CSS/HTML. Updating blogs is relatively easy, I copy and paste the div and change the content in my text editor.
I keep as much as possible on a single html file and make use of the sections tag so my file management and updates are relatively clean. This website has been an inspiration: https://john-doe.neocities.org/#home
Wow, thanks for taking the time to really dive in and share your thoughts about these things. I've honestly never thought about the music in relation to my interest in Japanese video games of that era, but I do feel the common thread there now. If you have any good recommendations for shows, music, or games that are in the same space as "early 2000's Japanese emotional drench", I'd love to check some more stuff out!
