If you like the idea of a URL shortener powered by Google but you're not really sold on the idea of having to install the Google toolbar to get access to it, the Goo.gl Bookmarklet takes care of that problem.
Like all bookmarklets, the Goo.gl Bookmarklet is unobtrusive on your toolbar and doesn't drain any system resources. Visit the site below to drag and drop the bookmarklet link onto your browser toolbar and start creating Goo.gl shortened URLS with the click of a button.
