Drop Canvas is a new service offering very simple file sharing. To share a file with someone just go to Dropcanvas.com and drag files from your desktop onto the Dropcanvas screen. You can drop multiple files onto the canvas if you want to. As soon as you have dropped files onto the canvas a url is created for your files or set of files. You can email that url, Tweet it, Facebook it, or post it on your blog. Anyone using that URL can view your shared files and download them.
Applications for Education
If you need to share files with students or colleagues and don't want to be bothered with email attachments, give Drop Canvas a try. One way that I might use Drop Canvas in a history course is to assemble a group of primary source documents on Drop Canvas then share the url for that bundle with my students that I want to read the documents.
