The Jetpack WordPress plugin is a set of plugins developed by Atomattic for WordPress.com blogs, but now available to WordPress.org websites, as well. Jetpack will cover many of your small business WordPress plugin needs. As of this writing, Jetpack is about a year old and has grown from just a few to fourteen separate features; all are free except VaultPpress.
Jetpack incorporates some of the best Automattic WordPress plugins that used to be available as separate plugins – Sharedaddy, Grunion Contact Forms, Wicket Twitter Widget, After the Deadline, and WP LaTeX.
