Sharing presentations online can help build a following and reach new people, even if you don't attend talks or meet your audience. There are several ways to share presentations, including using built-in sharing tools within presentation apps, streaming presentations in real-time, embedding slides on websites, or publishing them on platforms like SlideShare, Speaker Deck, and Scribd. Some of these platforms offer additional features such as clipping favorite slides, creating a presentation-focused landing page, or embedding specific slides from a presentation. The best option for sharing presentations depends on the desired outcome, whether it's to build a following, share ideas with a wider audience, or make a video of your talk.
