This is for strictly mildly interesting material. If it's too interesting, it doesn't belong. If it's not interesting, it doesn't belong.
This is obviously an objective criteria, so the mods are always right. Or maybe mildly right? Ahh.. what do we know?
Just post some stuff and don't spam.

Americans plugs are very strange
I always thought the holes were there for OSHA lockout/tagout locks.
I'm not American, but I've lived a few years in the US. I find it very interesting that the US invented the electric infrastructure that we use today, but they really screwed up a few things. Firstly, the connectors are far too unsafe. They are flimsy and have no protection from electrocution. Secondly, by using 120V as the main voltage, you need more current to do the same amount of work as a 240V system. Thay means thicker wires, more stress on the plugs, and greater fire hazards.
Shuko plugs FTW
The holes are only for manufacturability.
