I like it. The thing that I'm asking myself now is why do I like it (and other "humanized" drawings) ? I've always preferred accuracy over ambiguity, clean minimization over unnecessary clutter, shouldn't I prefer clean straight lines over something a human can draw on a sheet of paper? I'd never want to read a book written in human handwriting, so why is this appealing to me? Is it perhaps because the lack of optimization of the diagram contrasts and brings out the simplicity of the idea being conveyed? I could bring up some theories but can't say for sure.
