But thats the job of the copywriter. Making sure everything reads and displays. I think there is a bigger issue at hand and that is the fragmentation of skills going on. People are hiring more specialists when there is no need for one. A (good and experienced) copywriter with real world knowledge can actually do all those things you mention. Maybe its another buzzword like growth hacking, which I use to like and use, but now loathe.

Any list of good UX people I could research?
