Minus (Min.us) provides a simple way to share files with anyone. To use Minus just drag a file onto the blank Minus canvas. Once your file is on the canvas Minus will provide you with links to share your file with others. Minus will also generate a HTML code that you can use to embed your file into a blog or website. Those people with whom you share the url for your file can also download your file.
Applications for Education
Minus could be useful for students working on collaborative projects to quickly swap files that they need to share with each other. Minus also makes it easy for teachers to post documents online that they would like their students to read and discuss.
