If you weren't with us at 10NTC, you didn't catch See3 CEO Michael Hoffman announcing the winners of the DoGooder Nonprofit Video Awards in front of a packed lunch crowd in Atlanta, Georgia.

The lunch was good, but the videos were fantastic -- and we wouldn't want anyone to miss out on those.

Watch the 4 winning videos now!

• “Darius Goes West—A DVD in EVERY SCHOOL!” by Darius Goes West
• “'I Am The Wooden Floor'"” by The Wooden Floor
• “Join the Fight” by Canadian Cancer Society
• “What Kind of Planet Are We On?” by Rock for Equality

The winners were featured on the YouTube homepage that day, racking up more than half a million video viewsfor their causes!

Special thanks to YouTube, and our partners at Case Foundation, Flip Video, and See3!
