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&39;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&39;s YouTube channel to catch many more videos of some of their excellent speakers. Enjoy the crash course.
