In today's world it does not take long to be reminded that we cannot have nice things. Or maybe the gov't has their own bot army to wreak havoc and convince voters that actually, we really do want privacy-ending ID verification laws after all.
Just in the comments, right? That is where I see it. If I were the site owner I would just turn comments off. It was a cute idea when someone on HN suggested it, but without moderation open commenting becomes a cesspool in a hurry.

I would have burst out laughing at the absurdity of that experience. And then I might have apologized, because man how awful it must feel to be inside the head of someone like that.
Much of software is a trade. But above a certain level, it is engineering.
For example, in my discussions with electricians, they understand very well how to wire up a house. But they don't actually know very much about electricity. For example, they had no idea what I was talking about when I objected them running the phone lines through the same holes as the high voltage. I said that due to inductive coupling, the phone lines would acquire a 60 Hz hum. The phone lines had to be run at 90 degrees to the high voltage wires.
They had no idea what inductive coupling was, whereas that's freshman electronics material.
I wound up removing all the phone lines and rewiring them myself. No hum!
To further it, nobody cares until it breaks. Then they still don't care, they just want it fixed as quickly as possible, cost be damned once you get to that point.
Most? You mean all. 240V [0] as been the standard in the US basically since electrification started in the late 19th century. 120V has for all practical purposes never been a thing, it has always been an artifact of split-phase 240V. A deliberate choice to offer two voltages to every consumer.
[0] Okay, technically 240V did not become official until around 1967, but the split-phase design was there from the beginning. They capped it at 240V to stop the creeping up that had been going on in the earlier part of the century. This is why you still have a lot of people (not all of them old enough to have been alive in 1967, oddly enough) that refer to 240V as 220.
Sure, but that is the exception proving the rule. Not quite urban legend, you can find people on mikeholt.com who have actually seen one in the wild. Usually because of some shenanigans the local power company pulled to directly connect more houses by giving each one a phase of a three-phase feed.
