Previously relegated to the Google Toolbar and Feedburner, Google URL Shortener finally has a web site of its own.
Google URL Shortener (Goo.gl) now has a simple web interface where you input a URL and receive a shorter one. Nothing revolutionary here, but in addition to keeping track of your previously shortened URLs Google is touting the following:
Stability: We've had near 100% uptime since our initial launch, and we've worked behind the scenes to make goo.gl even stabler and more robust.
Security: We've added automatic spam detection based on the same type of filtering technology we use in Gmail.
Speed: We've more than doubled our speed in just over nine months.
Here's an added bonus tip from mattcutts: if you add .qr to the end of any URL you get a QR code instead of the URL. For example: http://goo.gl/LFwS.qr
But if you're not into the website, there's always the handy goo.gl Chrome extension.
