Finally Google URL Shortener is announced by google for public http://goo.gl/ You can not only shorten your URL but to also create a list of all the URL's you've used with their service. That list will save us so much time.
Hmmm... Why every company and individual is launching such services which already exists. Like Bit.ly Google=monopoly on net ?
Whenever Google does it, everyone thinks 'Omg! It's Google!' Google has that unique effect. Also, they are going to take over the world one day anyway!
Google's shortner defends whoever uses the links, it prevents malware links etc, goo.gl links thus should be safer + you get amazing stats on everything about the link
