To be fair, POST could mean a number of things. Are we talking in a webserver context? BIOS context? The POST Office?

I would guess 90% of "IT" people don't know what POST (in web context, maybe bios since they might have taken an A+ cert class lmao) means nor do they know how basic http or web servers work. Most of IT are help desk and do not know technology well but are comfortable enough to tell people to reboot, uninstall/reinstall stuff, reformat, google an issue they can't figure out.. Which is better than 99% of the world.
