Ask HN: Weekly Design Challenges for Developers?

While running a UI/UX design team for B2B startups, I do enjoy coaching developers from time to time. Helping them become better at recognizing why something feels ugly or off and how to find solutions quickly.

I wonder if people would be interested in a weekly UI/UX design challenge over email. And where I pick one or two submitted designs to provide deeper analysis and tips on how to make it better and why.
