Ycombinator has a great news aggregation website that is text only. You can find a link to it from the top of this page.

Exactly. I never understood all these "I don't enable js" comments. You kinda usually don't need to disable js on sites that are usable without js. And if you feel the urge to disable it, it is most likely that without js it's an empty page anyway.

It's difficult to tell whether the site will be usable with js before opening it, so js disabled by default provides better UX: it makes both usable and unusable sites usable. Then after the site proved itself, you can enable js if you know what you miss.

Hacker News?

Most sites are plain text with only a few exceptions like youtube. And even then video doesn't need javascript.

There are plenty, you're using the wrong navigational tools ;-)
