There are over 54 million WordPress sites in the world, and that number is split between the free WordPress.com service and WordPress.org open source installs. Both options have their benefits, one being self-hosted and completely customizable, and the other much easier to use with free hosting built right in.
But as WordPress.com grows, the network’s benefits grow too — benefits that independent WordPress sites normally can’t enjoy, unless they’re using a WordPress plugin by the name of Jetpack (created by Automattic). The plugin has proved to be extremely popular, and has just passed the 2 million download milestone (currently: 2,005,406).
Jetpack was created to extend the benefits of the network to independent WordPress installs, to make it so nobody is left out of features like WordPress.com Stats, email subscriptions, contact forms, WP.me URL shortener, Carousel photo galleries, and more. Reaching 2M downloads to date is a particularly impressive stat, as 1M of those downloads only occurred within the past four months.

More, from Automattic:
Jetpack provides feature parity between WordPress.org and WordPress.com enabling users to supercharge their self-hosted WordPress (.org) site with the power of WordPress.com. Other Jetpack features include Subscriptions, WordPress.com stats, VaultPress backup and security, Sharing, Gravatar hovercards, and more.
