I feel like a lot of people are harshing on the fact that this is not like, I dunno, geocities or something, but I just want to express some appreciation that an effort is made for those of us who do not want to execute arbitrary code just to read a blog entry.
One note - on that page, it seems that while the content is there independent of Javascript, the navigation is loaded (from three different domains) with Javascript. I suspect there's a more graceful way to fallback there.
Here's an example of a blog post written in 1999.io.

You do NOT need JS on to read it, by design.
