World's Languages Disappearing

Slashdot had some interesting links about the current state of human languages. According to National Geographic, every two weeks another language dies:

By 2100, more than half of the more than 7,000 languages spoken on Earth—many of them never yet recorded—will likely disappear, taking with them a wealth of knowledge about history, culture, the natural environment, and how the human brain works.

And then the New York Times ran a piece about how 83 languages dominate modern communications.
