FeedBurner is the largest feeds provider for almost all the sites out there. The latest feature from FeedBurner is the ability to publicize your latest feed updates to Twitter. FeedBurner will shorten your latest update by using the Google URL shortener which has the goo.gl url extension.

As per AdSense for Feeds Blog:

We’re now taking our distribution and analytics a step further by enabling the ability to automatically publish the feed items that meet your criteria to Twitter, using the Google URL shortener at goo.gl.

To get started, go to the Socialize service on FeedBurner’s Publicize tab and add the Twitter account to which you would like to post items from your feed. You can take the default settings and click [Save] to start socializing immediately, or use the options we offer to customize exactly which feed items are sent to Twitter and how exactly you would like them to look. The next time you post a new item to your feed it will be sent to Twitter (as always, make sure to ping FeedBurner whenever you update your feed so this process happens as near real-time as possible).

For full details on all Socialize options, see our FeedBurner Help Center topic.
