Oh god. I do a lot of PowerShell scripting at my place, and less than half my team is proficient in it. My co-workers who are almost never write comments in their scripts. Meanwhile, if it's anything that will live longer than ~5 manual runs, I spemd more time on comments and documentation than scripting.

That effort is valued, but I'm shocked that my team isn't more aware of the need for documentation. We literally experienced the "bus factor" situation a few years ago.
