This list strikes me as overly nitpicky. Certainly some of the bad example usage is a problem (e.g. mb vs. MB means two very different things, millibit vs. megabyte), but so much of this in practice just really doesn't matter.

Sure, if I'm doing a bit of formal writing, I'm going to do things correctly. But I don't see it as a problem for people to use odd abbreviations like "mtrs" or incorrectly pluralize as "kms" in informal writing. People will not have trouble knowing what you mean. No one is going to say things like "I drove 3 megameters over the past couple weeks". (Reading some of the longer explanations below seems to indicate that the author is not just talking about formal writing.)

And even in formal writing, a few of these are bit much, like good luck getting people to stop using electron-volts in favor of picojoules.

This just seems silly; it's hard to take this piece seriously, and all of the nitpicky arguments seriously undermine the (few) good arguments listed.
