Slideshare is one of the more useful startups launched in the past few years, as it means you can view slideshows without having to attend events. It is Youtube for Keynote and Powerpoint.

They include a comprehensive overview by Ogilvy PR, and a great slideshow by Adam Schoenfeld that takes a detailed look at running contests on Twitter.
