Google & Facebook launches URL shortner: goo.gl & fb.me
However, there is nothing to to be happy, since Google URL shortener is not a stand-alone service i.e., you can't use it to shorten links directly. Currently, Google URL Shortener is only available from the Google Toolbar and FeedBurner.
With limited space for tweeting, the URL shortener business has boomed, currently Bit.ly was leading.
Side by side with Google's URL shortner, Fb.me is also showing up in several tweets. However, it’s unclear how long fb.me has been in operation.
