Scribd acquires SlideShare from LinkedIn
So what's the point of sites like scribd and slideshare? They host your slides and display them on a crappy js viewer that's almost always worse than the browsers built in PDF viewer. They also enforce lock-in by preventing you from exporting to a portable format eg. PDF. On top of that some of the sites (i know for a fact that scribd did it at one point) charge you for the privledge of viewing their users' content, or force you to add to their existing catalog by uploading whatever docs you have. I'm not sure why anyone would use them over dropbox or google docs.
