They say that simplicity is the key to success. If that is true even just slightly, then this site is destined to the big time.
It lets you share videos found on YouTube using Twitter. The site has a shortening tool that works by trimming any YouTube URL you come across and turning it Twitter-friendly. Additionally, you can install the bookmarklet that is supplied and dispense with visiting the site each and every time you want to share a video a la Twitter.
What is the main advantage of shortening something this way instead of using Bit.ly or any of its zillion comrades? Well, the one advantage that it has is that the resulting links bear a “twtu.be” heading, so that any person who looks at it knows that he will be taken to a YouTube video, and not some place that is best left in the dark.
While the site is not exactly an all-expenses-paid trip to Novelty Island, it can turn out to be extremely useful. It all depends on your social web involvement. I would say that moderate web socialites upwards will find it a valuable tool. If you are one, you might as well put the wheel in motion and arrive at your own conclusions.
