Refactoring UI fails to explain WHY or provide evidence (e.g. A/B tests) that show their new designs even work. Let's take their most recent post for example (Remove Borders): https://twitter.com/steveschoger/status/897849211110273024 https://twitter.com/steveschoger/status/897849211110273024 The only explanation as to WHY is the before "look[s] really busy." That's quite subjective and unhelpful. There's no testing here, there's no remark on usability/accessibility, no discussion of color-blindness vis-a-vis background color tones, nor real justification for the change anyway. If you want to create pretty things without worrying about the consequences, they seem like a great resource. But hard to see it as more than a toy resource; professional UI resources do a much better job because they're made for real end users, rather than other developers e.g. UK Digital Project[0], US Digital Project[1]. PS - I'm not saying their designs don't look nice. I'm saying a nice looking UI design isn't a good yardstick for UI. I've created plenty of nice looking UI that users performed worse using.
