They're certainly fun to read, but does he actually think this is a remarkable insight into anything? You can pick any shape you want and then point out how logos are all trending towards that shape. Obviously by just selecting the logotypes that fit your argument.
It's a weak argument (what is it, anyways?) presented in an unhelpful way (criticizing a kid's school project?). Not that I buy into the idea that you have to be an artist to be a critic, but I do think your overall output to a community should be positive. You can either contribute critically by making good commentary or you can contribute productively by making good work. Eli does neither, and by the 3rd or 4th post you read by him it becomes painfully obvious.
Entertaining nonetheless, I suppose.
