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.
It's most frustrating with phone numbers. I picked up the habit of searching the random numbers that called me, to try and find out if they were possibly important. I used to get a bunch of spam sites that clearly existed to profit off me making those searches.
Both Google and DDG have removed those spam sites, even though they were useful at times. Google will tell me the number is in some random PDF that contains a few of the digits, then no other results. DDG will say the top result is my local police department, something that freaked me out the first few times.
