It's especially important for blog posts like this to have a very obvious timestamp on the page somewhere. This is a contemporary post but I couldn't verify that until I went into the archive view.
There is a worrying trend in minimlaist design lately. It seems that more and more blogs are leaving out information about the author (less impotant here) and when the post was created, two very important pieces of information!
The same happens on a large percentage of open source projects. Dear project maintainers, if I go to your website, one of first things I want to know is when the last version was reased and perhaps what's new in this rease.
Sometimes you have to dig deep into the online docs to find this info.
