I don't support the nonstandard use of commas as decimal points in my software, so that's not an issue for me. That's a hill for the Europeans to live and die on. "Gotta be different from everybody else" has a price.
Isn't it the US that is the "different from everyone else" in this context?
Just how shut-in are you?
Regardless, it's goofy. Everybody should agree on one or the other, and it's too late for the other 73% to switch.
News flash: these people hurt you, too.
Life is finite, but unfortunately, bullshit like "Hey, let's use commas as decimal points, LOL" isn't.
