There are many reasons why you would opt for a WordPress.org self-hosted installation for your blog or website, but there are also advantages to the hosted WordPress.com solution too. Get the best of both worlds with this plugin.

Jetpack “supercharges your self-hosted WordPress site with the awesome cloud power of WordPress.com.” This helps to really speed up your site with a number of additional helpful features.

You get WordPress.com stats for free, as well as a Twitter widget, Gravatar hovercards, WP.me shortlinks, Sharedaddy, LaTeX markup language, After the Deadline (spellcheck and grammar check), and shortcode embedding with YouTube, Vimeo and SlideShare.

Jetpack itself is completely free to download and install. In the future, the developers aim to add some “premium” features that will come at a cost.

Go to JetPack.me for more information and to download the WordPress plugin for your own site.
