Industry Week's Mark Gottleib writes about the most important skill he thinks today's workers should have.

It's language.

He writes: "Young Americans are allowed to leave universities and graduate schools with fancy degrees but no working knowledge of German, Chinese or Japanese. A fair percentage can't even speak English as well as their counterparts overseas, and horrifyingly minuscule numbers can write an intelligible sentence. Does anyone in the United States under the age of 35 know the difference between 'your' and 'you're' anymore?"

Journalists can easily answer that last question -- but can you answer it in a language other than English?
