Posted by at 8:09 PMGoo.gl. Right now this feature works only in two of it's services, Google Toolbar and Feedburner.
A little more info about Goo.gl from the Google blog:
"First, we think people who use the Google Toolbar and FeedBurner will benefit from a shortener that is easily accessible — making it faster and easier to share, post and email links. Second, we've built this on Google's global infrastructure to offer the following benefits:
Google URL shortener is not a stand-alone service; you can't use it to shorten links directly. Currently, Google URL Shortener is only available from the Google Toolbar and FeedBurner. If the service proves useful, we may eventually make it available for a wider audience in the future."
- Stability: Google's scalable, multi-datacenter infrastructure provides great uptime and a reliable service to our users.
- Security: As we do with web search, shortened URLs are automatically checked to detect sites that may be malicious and warn users when the short URL resolves to such sites.
- Speed: At Google we like fast products and we've worked hard to ensure this service is quick. We'll continue to iterate and improve the speed of Google Url Shortener.
