> A UI designer has no say about responsiveness (latency). A UX designer does That is definitely not true. UI design encompasses usability, including interactivity, feedback, animations, etc. Otherwise it's just graphic design. I think the term UX was defined to go way beyond those concerns, and into areas from marketing, branding, copywriting, all the way to what the actual product is, how it is offered, even pricing. Some simple examples: timing and content of emails, purchasing options and how they are displayed, how multiple platforms (mobile, desktop, snailmail, phone) are tied together, content strategy. You can see that aspiration reflected in the designer responses in the beginning of the article: they are the ones mentioning the business side, and not the managers.
