The Place of UX
7.5.2019
Every time "UX" comes out of my mouth or is typed by my fingers, I think, "did I just use that term correctly?" It feels like such a big and loaded term these days, that perhaps the way I use it only contributes to the confusion. Ryan Singer frames that problem well:

Jeremy on the divide between the core languages of the web, and all the tooling that exists to produce code in those languages:

I like the this wrap-up statement from Hidde de Vries:
In modern browsers, our markup becomes an accessibility tree that ultimately informs what our interface looks like to assistive technologies. It doesn’t matter as much whether you’ve written this markup:
in a .html file
