Jetpack by WordPress.com

Here comes yet another product from Automattic and WordPress.com team – Jetpack.

This is a WordPress plugin that brings WordPress.com goodies to your self-hosted WordPress site.  The project is starting off with just a few, most requested, bits of functionality, but according to this blog post more is coming.

For launch we’ve brought eight of the most-requested features into Jetpack as one easy bundle: Hovercards, Stats, After the Deadline, Twitter widget, shortcodes, shortlinks, easy Facebook/Twitter/WordPress sharing buttons (Sharedaddy), and for our fellow math nerds, LaTeX. We’re excited about this initial set of features, but we’re even more excited for what’s coming down the road.
