Then perhaps you shouldn't be giving design advice.
"I am a designer. I am not a programmer. Here's how to build a half-decent web application in half an hour. First, download PHP..."
All due respect but the author knows just enough "design" to be dangerous, so to speak. Bootstrap is well-designed (dull, but well-designed), and the author's redesign is more of an "un-designing". Arbitrarily adding fonts, colors, and background images take a perfectly usable layout and make it look like something straight out of 2002.
(Do people still use "pimp" as a verb non-ironically?)
[Edit] A note of clarification: I mean no disrespect to anyone doing web design, whether their job title starts with a capital-D or not. I just wouldn't recommend that most of them dole out advice about it.
