I really like that I can link to a specific slide on Slideshare with the dead-simple approach of adding "slash-slidenumber" to the URL. Thanks folks, that's doing it right!
So if I happen, quite hypothetically you know, to want to send someone with a short attention to a slide show, I know he's not going to click through to the slide I want him to see. But since I can send a link to the exact slide, I can hope to capture just enough attention to get somewhere. For instance, I like this summary of teacher gift ideas.
