This deceptively simple page is called "Common Errors in English". It is a pretty darn comprehensive collection of, you guessed it, common errors made by English-speaking and writing human beings. I've been aware of the site for no more than five minutes and I've already learned of two mistakes I've been committing for years.
Big-ups to Washington State University English professor Paul Brians for posting this indispensable guide to the language we all frig up on a daily basis.
(That's right, he's a WSU prof. My mom would be so proud of my open-mindedness. But only after she celebrated/flaunted the merits of her Cougar brethren.)
[Stuck in my head: nothing right now, but yesterday morning I woke up with Modest Mouse's "The View" firmly lodged in my brain. Which is strange, because I hadn't heard so much as one note of a MM song for a long, long while. But lo and behold, there it was. Enjoy.]
PS: More, better content coming soon. Stay tuned, mes amis.
