Ethan's on stage at Poptech, burning the place down with a fabulous speech about what geeks can do to save the world. Very smart, very funny. Here's his summary of his former work at Geekcorps:

"To benefit from the Internet you need geeks.
"There are few geeks in Africa.
"Geeks beget geeks.
"Geek+ plane ticket = geek in Africa"

or, even better, his summary of the crisis between investing in technological and innovative solutions vs. meeting human needs: "plantains or pcs? plantains and pcs!"
