A lot of the examples in here, I can't find? Like, I looked around for the new smart folder with the cog icon, where is it on my mac? Same with save as check, where is that? Also I'm pretty sure (although I can't find it) the save as with the up arrow is save as out to something? The ones I do find, all make perfect sense and work pretty well for me, they're not totally perfect but I'd never thought about them much before this post and I use them almost exclusively. Look at all his new for example, see new finder window? Look at the box around it, then open your window menu at the top of your screen, see how minimize has the same box around it? If you go though those icons set, most of them have: primary, secondary and sometimes tertiary visual clues. I dunno, I read that blog post and it doesn't really jive with me. I'm sure they could stand to clean it up a bit, I don't know I'm not a designer, but I'm certainly glad they are there!!! ¯\_(ツ)_/¯
