Sorry, but it is. Simple test: open a page and view source. Do you see HTML or do you see a big chunk of obfuscated JavaScript?
Browsers today are wicked fast at rendering HTML. They are ungodly slow on anything that replaces HTML with JavaScript. A text-heavy site such as LessWrong is very well served by pure HTML with a small scattering of JavaScript here and there. LessWrong 1.0 isn’t perfect markup (too many divs and spans, too little semantic markup) but it is much better designed for speed than 2.0.
