I found a big part of the appeal with tools such as Excalidraw is that people are still more willing to engage with your content because they think that its made by hand.

Compare a piss-tinted LLM-generated diagram with 80 pipes, flows and generic names everywhere to a seemingly hand-drawn sketch.

I have had my Exaclidraw connected to an agent through their MCP and I have gotten way more attention/time/reads on both blogs and papers because of the illusion of being human-made/hand-drawne making it more palatable.
