The mayor of Minneapolis just declared a “Mystery Science Theater 3,000” day. The future of our civilization demands that we all be on the same page about that comma. It is time to decide which spelling shall reign supreme.
While I am an advocate of the Oxford Comma, I am not a fan of numerical placeholder commas in numbers under 10,000. Four digits are easy enough to distinguish without it. It looks particularly weird when the number is also a year.
I don’t remember where I read it but Joel once said that the “3000” was there because making products sound futuristic and amazing usually meant tacking a “2000” at the end. And while it wasn’t meant to represent a year, we were all slowly rolling toward the year 2000 which would then cease to be futuristic-y so he bumped up to 3K.
Years, serial numbers, and reference tagging all prohibit the use of commas. “3000” can fit in any of these. It certainly isn’t a count of something.
