It’s getting easier for designers to become engineers. That’s a good thing, but it should be even easier. Design should be the hard part.
This is a great post, and something I think about often. I can read and write a lot of HTML and CSS, and can read some JavaScript. I don’t know anything about design, but I’m confident in my ability to avoid ugly mistakes by putting as much consideration into what I don’t include as I do into what I do include.
As an aside, Medium is a beautiful site with consistently solid content by thoughtful and articulate people.
