So? Hacker News is probably one of the worst designed websites I have ever used both from an usability and aesthetic perspective. It has nothing to do with the fact that this blog post is nearly unreadable.
I agree - the grey text is hard to read. Mostly that's by design; down voted comments are supposed to be hard to read. But when someone starts a thread with a comment, instead of an external link, they grey text is weird and hard to read.
