After a brief disappearance, short URLs are back in Google Maps. This was one of the most popular experiment from Google Maps Labs and it's now a standard feature. Just click the link button next to the search box and click the "short URL" checkbox. The new short URLs use g.co, a domain
recently acquired by Google. All the URLs that start with "http://g.co" send you to Google domains, while
http://goo.gl/ continues to be a public URL shortener.
Google Maps is the service that generates very long URLs with many unnecessary parameters, so the short URLs are useful not just for posting a Twitter message or sending a text message, but also for writing an email, a comment on a blog post or for adding a Google Maps URL to a document. Google Maps also needs to automatically change the URL from the address bar, so that you don't have to use the permalink button.
