Slip SlideSharing Away

I'm not sure they are going to be getting any $1.65B offers in the near future, but I think this site has some utility. Essentially, it's a PowerPoint version of YouTube.

From their site:

"SlideShare is a free service for sharing presentations and slideshows. You can upload your PowerPoint and OpenOffice presentations, tag them, embed them into your blog or website, browse others' presentations, and comment on individual slides. It's a great way to share your ideas with others, or to learn from other people. And it's free."
