Digital whiteboarding tools are close, but I think they miss some of the magic of working in a shared space with an analog too.
I can make more complex drawings in excalidraw than I could on a really drawing surface. I suspect that leads to simpler drawings and thus simpler designs.
1) it’s prettier and less messy 2) the digital markers are never dry 3) it encourages more edits and changes
I basically start all my technical designs in excalidraw now
