Hashify – your entire document in a URL

"At first glance, Hashify is a web page where you can write notes. Notice the short URL just above the editor pane, next to the Twitter link. When you start adding text in the editor pane, you'll see that the URL disappears and is replaced by "Save.Shorten. Share". Click those words, and you get a new URL. That is the URL for your document. You can send the URL to anyone, and they can follow the link to read your document."
