Captology videos

B J Fogg at Stanford writes:

My Stanford students have created short videos (averaging 2 minutes) that show how Web 2.0 services persuade people and change their behaviors. The videos are interesting -- and sometimes funny. I'm inviting you to help evaluate some of these videos before December 4th. You can rate one video or twenty. The choice is yours. The videos with the highest rating will be featured in the Captology Film Festival on December 7th at Stanford. You're invited to join us at that event. For more info, see http://tinyurl.com/yap7fe .
