If you think an apostrophe was one of the 12 disciples of Jesus, you will never work for me. If you think a semicolon is a regular colon with an identity crisis, I will not hire you. If you scatter commas into a sentence with all the discrimination of a shotgun, you might make it to the foyer before we politely escort you from the building. ...Read the whole thing. Now, I'm no grammar Nazi. I claim no great insight into the workings of the English language. When I worked at The Magazine, I once drove an editor into wrath by consistently confusing state abbreviations with postal abbreviations in my articles. In other words, I'm in no place to judge those who write in LOLspeak. But I do have a little grammar book that I pore over from time to time while plodding on the treadmill, and I've been known to listen to the Grammar Girl podcast while mowing the lawn. Those of us in the creative writing field have a higher bar to clear than Twitter addicts -- especially if we don't want a slush reader to pitch our efforts into the circular filing bin.
Everyone who applies for a position at either of my companies, iFixit or Dozuki, takes a mandatory grammar test. Extenuating circumstances aside (dyslexia, English language learners, etc.), if job hopefuls can't distinguish between "to" and "too," their applications go into the bin.
Of course, we write for a living. iFixit.com is the world's largest online repair manual, and Dozuki helps companies write their own technical documentation, like paperless work instructions and step-by-step user manuals. So, it makes sense that we've made a preemptive strike against groan-worthy grammar errors.
But grammar is relevant for all companies. Yes, language is constantly changing, but that doesn't make grammar unimportant. Good grammar is credibility, especially on the internet. In blog posts, on Facebook statuses, in e-mails, and on company websites, your words are all you have. They are a projection of you in your physical absence. And, for better or worse, people judge you if you can't tell the difference between their, there, and they're.
