Google earlier added a socialize option in FeedBurner to help web publishers automatically publish their RSS feeds to Twitter. You had to connect your Twitter account to FeedBurner and a tweet would be sent out as soon as any new article became available in your feed. we are also enjoyed this feature and used the method to auto post latest posts to twitter. For facebook, we used facebook notes RSS update feature. Unfortunately both options are discontinued and the site owners and bloggers need to find some other alternate options to solve the problem.
We are currently using twitterfeed to auto publish post to Twitter, Facebook and Linkedin.
