Let’s talk about how the web is a complete clusterfuck being held together by the digital equivalent of this post’s titular items.
The web of today would probably be, on the surface, not really recognizable to someone who was magically transported here from 20 years ago. Back then, websites were mostly static (pace the blink tag) and uniformly terrible-looking. Concepts like responsiveness and interactivity didn’t really exist to any serious extent on the web. You could click on stuff, that was about it; the application-in-a-browser concept that is Google Docs was hardly credible.
You see, I am of the strong opinion that the client-side development architecture of the web is ten different kinds of fucked up. A lot of this is the result of the “architecture by committee” approach that seems to be the MO of the W3C, and a lot more seems to be just a plain lack of imagination. Most complaints about W3C focus on the fact that its processes move at a snail’s pace and that it doesn’t enforce its standards, but I think the much larger problem with the web today is that it’s running on 20-year-old technology and standards that were codified before the current iteration of the web was thought to be possible.
