On his Web 2.0 Teaching blog, Alan A. Lew points out a new mashup tool from Slideshare: Slidecasting. A Slidecast synchronizes an uploaded PowerPoint presentation with an MP3 audio file (that must live somewhere else on the web). Slidecasts do not incorporate video of the presenter—compare with Zentation, a web-based mashup that does include presenter video—but Slideshare's embeddable results look very slick.
