This article isn't wrong, but it's so unhelpful that I can't see anything to recommend it. It's just a rant. The description of a poseur designer is so vaudevillian that everyone, regardless of how much they suck, will look at it and say, "Gosh, I'm sure glad I'm not one of THOSE idiots." It's true that bad designers devalue the profession, but this article doesn't shed any light on the problem or bring us any closer to solving it.
I totally disagree. Bad designers don't devalue the profession, they show the real value of good designers. Anyone who has hired a bad designer will immediately see the difference a good designer makes.
