Yeah this is ludicrous. There are thousands of designers making a killing in tech who don't show this level of refinement, effort, or robustness in their thought.

He's just being a jerk to be a jerk.

+1 I thought it was quite impressive until reading that comment from someone who works in the design field!

Don't believe that guy, it's still impressive.

Of course design people* don't like good concept art for a tiling wm. It's not "modern", emphasizes work instead pointless high rez stock photos, and acknowledges the desktop.

*not all design people, just a certain flavor

1. I'm actually a big fan of tiling WMs, I use xmonad on my personal archlinux laptop.

2. "concept art" for a tiling wm makes no sense, because as you point out, it is first and foremost something that is work focused. This is why you build functional prototypes.

I see you're also a big fan of numbered lists.

Concept art for a tiling window manager certainly does make sense. Especially if you want to define the appearance of one.

It is, he's just finding reasons to be an asshole. It's only tough because people like him make it needlessly tough due to some inferiority complex.
