I know we're not supposed to go off on website stuff (per guidelines: "Please don't complain about tangential annoyances—e.g. article or website formats, name collisions, or back-button breakage") but jfc who thought this design was even remotely a good idea?
Somebody who doesn't want the same bland, boring, homogenized look that every other website in the world is using?
Personally I like a site that shows a bit of personality. It's quirky, but for an open source web framework written in Guile, it looks about perfect to me.
