I'll let SlideShare speak for themselves. I'm posting a blurb from their about page below. Unlike most Web 2.0 site, SlideShare actually describes what they do in real-world business terms.
Why SlideShare Matters to Associations
It's a place to share your conference or training speaking materials and also find many other presentations pertaining to your industry? Have speakers from your conference uploaded their presentations here without you knowing. Are there awesome presentations uploaded here that could be a lead to an excellent future speaker?
