While Google may not have intended their new Goo.gl short URL service to be used anywhere other than the Google Toolbar, I doubt they’re too upset about developers figuring out how to tap into it.

Three extensions have already popped up in the Google Chrome Extensions Gallery which offer Goo.gl truncation in your browser. ChromeMUSE, which I’ve been using for a little over a week, pushed an update last night which added Goo.gl support.

The other two extensions are a standalone goo.gl shortener and a combination shortener/share on Twitter extension. All three provide a similar alert box which displays the newly-created short URL is highlighted and auto-copy the link to your clipboard.

I’m partial to ChromeMUSE because it also supports other services – and because its toolbar button resides inside the Omnibox. I can’t explain why, but to me it just feels like the right place for a link-shortening extension to park itself.
