I'm a bit tardy in reporting this, but better late than never: the endangered language research team of K. David Harrison and Greg Anderson, in collaboration with National Geographic, have started a YouTube channel for their Enduring Voices mission. (Read more about it here and here.)
The last time I'd mentioned Harrison and Anderson on Language Log, back in July, their documentary The Linguists had just received an Emmy® nomination for "Outstanding Science and Technology Programming". Since then, Harrison's book The Last Speakers: The Quest to Save the World's Most Endangered Languages has been published (in September), and there was an associated splash in the media (in October) concerning Harrison and Anderson's discovery of the 'hidden' Tibeto-Burman language Koro. Sorry, I've been away from my desk. I'll try to do better.
