Hashify does not solve a problem, it poses a question: what becomes possible when one is able to store entire documents in URLs?
via Hashify.
Try contemplating this for a few minutes. A whole document. In a URL. Not a link to a document, the actual document. Encoded and stored in a URL. Thousands of characters reduced to a handful in a short URL.
Imagine a blog that is just a store of URLs. A messaging system that trades links instead of text. A commenting API that just delivers URLs.
In education there could be student portfolios that are literally a collection of links. Exam submissions that require only sending the teacher a URL.
The possibilities seem endless and exciting. You can give it a try at http://hashify.me/.
