Jay Cross posted this review on SlideShare. He didn't give it high marks, noting the margins gave him troubles and the format didn't support audio. I agree, if you saw my earlier posts I had trouble with the margins, but actually think that concept of sharing power point slides as easily as a YouTube video is a really good one. I will continue to use SlideShare to post slides on the web and I am confident that audio support will either come from the company or as a service from another company. That's what is so great about the web2.0 world.
