every voice menu I've ever heard has called it "press pound sign for..."

In Germany, the phone key # is usually called "Raute". And it drives me nuts for decades, because a Raute is a Rhombus. But people have misnamed it for decades, and so it became an official name. It has several other, better names, see https://de.wikipedia.org/wiki/Doppelkreuz_(Schriftzeichen).

> the phone key # is usually called "Raute". ... because a Raute is a Rhombus.

That's because the original sign on the telephone was NOT a # but ⌗ (Unicode: U+2317 viewdata square). Often inclined it looks like a rhombus ⌗ °

The # is only a replacement symbol, which made it to the computer keyboard because of it's American use for numbering things.

The official German name I use for # is Doppelkreuz (literally "double cross")

Doppelkreuz is also a name for other symbols like the Patriarchal_cross but that's hardly relevant in an IT context.

When I got started on Unix I thought "hash" was programmer slang, like "bang" is for the exclamation point. I picked it up and started using it out of a desire to join programmer culture. Now I've just learned it was a Brittish-ism :-)

...and one we've exported to the world through the hashtag but ironically thanks to Chris Messina, an American blogger...

The official name for the exclamation mark or bash character is a pling. I learnt that from a school friend many, many years ago and very few people seem to ever use the term besides me and (presumably) said friend...

"The official name for the exclamation mark or bash character is a pling." [my emphasis]

It seems that, unless I set up an account, I'm missing some of the information presented; nonetheless, this does look more like a definition of pling than a definition of exclamation mark.
