I like the wonky, hand-drawn looking style. I think it fits well beause usually if I use a diagram it's not 100% precise and accurate, but more a high-level illustration. The wonky style conveys the approximate precision of the presented concept.
Also, and that's personal, I think it's cute.
I agree 100% it's personal, wasn't trying to imply anything else, but for me the style takes away from the actual content and makes it harder to read/grasp.
I thought they were saying the tool is wonky looking, but <shrug>?
One person's bug is another's feature.
I agree with you. I think the 'wonky' comment was more to serve as justification for the plug than an actual criticism of Excalidraw.
Excalidraw is my favourite thinking tool, and the style it produces is just the right level of limiting, disarming, and professional at the same time.
