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.
