Since we're already complaining about "New thing Bad, Old thing Better," why oh why does this blog require third-party JS from three separate domains (s3.amazonaws.com, fargo.io, and scripting.com) just to render a page of static text with minimal styling? The only user-visible thing I can see that uses JS is the section folding thing, which can be done with no JS using the <details> tag on modern-ish browsers, or a tiny chunk of inline JS if you want to support older browsers.
