I was not a fan of the old icon[1], but the new one isn't better. Way too much detail on the new icon at smaller sizes.

That’s how much detail OS X icons are supposed to have. (Have you looked at the apps that come with the OS?!) Smaller versions with less detail are used for smaller sizes.
I wish more app developers would actually have such awesome icons. But HN has to complain. Of course.
