Automattic, the company behind WordPress.com has given its Jetpack plugin a big update.
Think of Jetpack as a bridge that brings functionality from the hosted WordPress.com service to self-hosted WordPress.org blogs. It adds in lots of the core WordPress.com features, such as stats, social comments, email subscriptions and more.
With Jetpack 2.0, the plugin gets lots of new functionality, including the ability to automate sharing posts to various social networks.
With Publicize, users can configure their self-hosted WordPress blogs to share posts with social networks including Twitter, LinkedIn, Facebook, Yahoo and Tumblr.
