Short.nr™ is a simple URL Shortening service with a twist. It comes with #hashtags, domains, and link notes. This is much unlike the average URL shortening service that only shortens links. Each link here is saved for posterity with accompanying notes and short URL.
Currently, only registered users with accounts can shorten links.
From Wikipedia
URL shortening is a technique on the World Wide Web in which a Uniform Resource Locator (URL) may be made substantially shorter and still direct to the required page. This is achieved by using a redirect which links to the web page that has a long URL.
For example, the URL "https://example.com/assets/category_B/subcategory_C/Foo/" can be shortened to "https://snip.ml/Foo", and the URL "https://example.com/about/index.html" can be shortened to "https://snip.ml/h2iBY".
Often the redirect domain name is shorter than the original one. A friendly URL may be desired for messaging technologies that limit the number of characters in a message (for example SMS), for reducing the amount of typing required if the reader is copying a URL from a print source, for making it easier for a person to remember, or for the intention of a permalink.
