The site SlideShare.net is a hosting of slides, which sometimes compared with video hosting Youtube. Here you can upload slide files with such formats as PDF, PowerPoint presentations, OpenDocument and Keynote. Downloading can be done in private mode, so that uploaded files are accessible only to you and chosen users, you shared the link with, or in a public mode, when your slides are available to all visitors.
Initially, SlideShare was designed to make it easier for company employees working with slides and presentations to share files with each other. Subsequently, the benefits of hosting were appreciated by other users, as a result of which many presentations on modern SlideShare are laid out more for entertainment than for business. Also, downloaded files can be commented and evaluated.
