Two months ago, back when I was in Singapore – and representing my previous employer, I presented at Crowdsourcing Week on Crowd Advertising Success Stories and Challenges. The video's now live, and the presentation's on SlideShare, so now you can follow along and relive every crowdsourced moment. Or something like that. You can also head to Crowdsourcing Week's YouTube channel to catch many more videos of some of their excellent speakers. Enjoy the crash course.
