A while ago Kumara Sastry introduced me to the beauty of SlideShare. I have been using SlideShare services for a while in the little blogging I do to upload, share, embed, and display some of my presentations. The other day David E. Goldberg introduced me to Scribd. The site takes the SlideShare idea further and allows you to use their services as a publish-it-yourself site. It also allows you to embed the document on your page, as SlideShare does. A slightly different flavor of the publish-it-yourself idea is Lulu. Here, the gears are more oriented to have an online cheap publisher where you are your own editor. As I said, a different flavor for a different purpose.
