Slideshare (
Slideshare is an easy, popular, and free tool for putting PowerPoint or OpenOffice slides, as well as many other file formats like PDFs and Word docs, online. The viewer doesn’t need to have PowerPoint or whatever app the original file was created with, they only need web access (free Slideshare accounts only allow for public uploads, meaning they will be available to everyone. For private uploads, one needs to upgrade to a Pro account, which starts at $20/mo.).
