I'll try to do that, thanks. I'm not a programmer or even a 'tech person', that's why I decided to use a framework that takes care of the basics so I can just focus on making the site look 'personal'.
The scriptless web
No.
JS was used in the 90's, but the web wasn't oversaturated with it like today, and there were often Lynx-friendly version of pages, or sometimes even "no frames" versions. But even when the webmaster went full retard and used only JS for navigation, it was still possible to look at the page source and find the HTML link, so you could still navigate those sites.
Not sure why you're lumping cookies in there. Those are another thing altogether, and even Lynx supports cookies (but not JS, frames, CSS).
Cancer. Reinvent the wheel again, no-project.
Your system is shit.
What's the point of this post? It's a PERSONAL website, so the CSS should also be PERSONAL. Unless you want your site to look like just every site out there.
never gonna make it
Javascript is used for things which could be done easily though server-side templating slowing down your browsing experience. There are legitimate use cases for JS, but they should always involve improving your existing HTML, not replacing it. Look at twitter for a particularily bad example of JS. You don't need client-side scripting to display 140 character messages, and maybe a couple images.
Also security/privacy, but those concerns pale in comparison to how fucking slow JS/DOM manipulation is

Which could be implemented in what, 20 lines of JS? Auto-updating doesn't excuse the monstrosity that is twitter.com
