Thanks for the feedback. I made the text darker.

If you're in the mood for constructive feedback, there's something that makes that page difficult to read. It could just be font rendering at that tiny size, it could be the contrast with the line spacing given the text size. Either way, taking the font-size up to 15px makes it readable, for me.

Thanks, I'll look at adjusting the base font size as well. I agree it's a tad small.

It's also a good idea to use font-size:100% let the browser/user decide what font size to use , yours is a bit small. It should not break your layout. nice article.
