Ya ya There is one more URL Shortner in the List of URL Shortner’s, After goo.gl its now youtube. Youtube came with its own URL Shortner youtu.be which is especially meant for youtube videos.
In their blog they have mentioned some things
we’ve just launched youtu.be as a shortener for YouTube video links — and nothing but YouTube links — so you can rest assured that when you see a link with this URL, you are indeed about to click on a YouTube video. (Also, because the link contains the ID of the video you’re going to see, developers can do interesting things like show you thumbnails, embed the video directly, or track how a video is spreading in real-time.)
You can read the original post at their blog.
