I'm constantly DM'd at work about how I'm able to create the "cool drawings" in my blog/wiki posts, and I enthusiastically point to excalidraw.com.
I have a background in vector illustration, which is all about creating subpixel-perfect designs. I'm also a bit of a perfectionist, which I think a lot of people here can relate to. I mention this because the reason Excalidraw really works for me is that it frees me from worrying about design. When you literally can't create something that looks "perfect", you're freed up to just sketch your idea without worrying about the visual representation.
