He has way less readers than an almost infinite amount of blogs with 1/10 the lines of code so your argument proves nothing. And today Josh is losing a lot of readers that can't *READ* his blog. Because it is terribly developed, although it looks shiny (when it unfreezes).
My argument is that Josh has a lot of readers because it's clear that he puts a lot of time and effort into writing a great blog, and the code plays an important part. Obviously code isn't crucial to writing any successful blog (although in Josh's case it is) but my guess is that most of the people who see their hacked-up-and-spit-out homegrown blogging system as a positive put a similar amount of effort into that content.

Anyway, you seem to have an axe to grind here, so I'm ducking out. Have a nice day!
