TechCrunch is covering an interesting new startup - SlideShare. It helps solve the problem of sharing PowerPoint presentations without having to e-mail slides around. Just publish your presentation to SlideShare and you can view it on the web, embed it in your blog, like videos and YouTube. There are a few limitations right now, like 20MB limits, editing restrictions, etc. but the SlideShare folks are working them out as we speak. I'm looking forward to seeing more of this!
