SlideShare is a website where users can upload, view, and share presentations and documents. Users can share their work privately with friends or publicly for anyone to see. Presentations can be embedded on websites or blogs and allow others to download the original file. SlideShare allows users to search for presentations by category, upload files instead than sending emails, and tag presentations to make them searchable for others. Students can use SlideShare to share class projects, register an account, upload files, embed presentations on other sites, and use hashtags to make their work easy to find.
