wasn't this basically the idea with CSS (and user CSS), "semantic" HTML and JS as progressive enhancement? those were pretty exciting ideas (IMHO), and with modern CSS there's no reason they shouldn't look good either... what ever happened with that?
Yeah, we should not be visiting those sites. Give our attention and currencies to the sites who care about their users.
I guess one good thing about AMP is now I know what sites to do my best not to use.
