Democracy Now! has an interview from Netsquared conference with Hong Eun-taek, Ethan Zuckerman (who's a really *great* guy!) and Saori Fotenos who's teaching kids in the favelas* of Rio to blog. From the interview:

HONG EUN-TAEK: We launched our site six years ago with four full-time staff members and 727 citizen reporters, and it has grown into a big operation with actually 43,000 citizen reporters.

AMY GOODMAN: What do you mean “citizen reporters”?

HONG EUN-TAEK: Our statement is that everyone can be a reporter, so news stories can be written by citizens who are expert on their lives, so they can write about their lives and what they believe and what they want to see in the society.
