I am not really a nitpicker and am impressed with the subject matter and responses to this point. I was saddened when I taught college classes a decade ago at the state of the language. This is also an example-a well respected institution of higher learning and 1)differenciate (yes you can find it on the web but not in M-W or OED the definitive word on our language) and 2. not possessive american's but plural americans. Yes-thankfully our language is evolving but we must accept some basics-unless it is for satirical or abstract purposes. I realize the point of the forum is a free exchange of great information for all, but I am sure when this scholarly paper is written, that the spellcheck will not catch their errors
