IMHO, using the word "CRAP" to describe good practices seems like a bad idea. I thought the article was going to be a rant about some UIs the author didn't like... instead it was useful advice. I'm glad I clicked through, but "CRAP" didn't help that.
This person didn't invent the term CRAP to define good design; it's been around for longer than I can remember.
It's still a poor term for positive reinforcement...
...and makes it nearly impossible to separate the crap from the CRAP!
Fair enough. But the people that need basic advice like this might not be aware of the term, and might not read the article as a result.
On the contrary, I think people are more likely to read it because of the "lol they said CRAP!" reaction. I guess that was why the term was 'invented', as opposed to PRAC or RAPC or another less-silly combination.
